Glenoid dysplasia. A case report and review of the literature.

Glenoid dysplasia is a rare congenital abnormality that may be associated with vague shoulder pain, limitation of motion, and weakness of the upper extremity. In many cases it is an incidental finding on chest roentgenogram, and high-level function is usually possible before the onset of symptoms or degenerative changes. The case of an 18-year-old collegiate football offensive lineman who developed symptoms secondary to previously undetected bilateral glenoid dysplasia is reported. Roentgenograms demonstrated dysplastic scapular necks, and arthrography showed a deformed, constricted shoulder capsule. Magnetic resonance imaging defined the extent of the cartilaginous anlage, and arthroscopy demonstrated progressive articular cartilage degeneration. Although treatment alleviated the shoulder symptoms at low-level activities, the patient was unable to successfully compete under the extreme demands of an American football lineman.

Early and late loosening of the acetabular cup after low-friction arthroplasty.

Between 1971 and 1979, 680 low-friction arthroplasties of the hip were performed in 598 patients. The average duration of follow-up was twelve years and eight months. Sixty-one acetabular cups had loosening as seen on roentgenograms eighteen years postoperatively, resulting in a total cumulative probability of loosening of 19 per cent, according to survivorship analysis. In twenty-nine cups, the loosening appeared within ten years after the operation (early loosening) and in thirty-two, more than ten years after the operation (late loosening). Early loosening was associated with deficient structure of the bone of the acetabulum, a previous congenital dislocation of the hip, acetabular fracture, or acetabular protrusion in all instances (p < 0.01). Late loosening was associated with the depth of acetabular wear. Of the thirty-two cups that had more than two millimeters of wear, eighteen (56 per cent) had loosening on the roentgenograms (p < 0.001). In hips that had early loosening, migration was the most frequent finding, and its rate of progression was higher than in hips that had late loosening (p < 0.001). In late loosening, a complete bone-cement radiolucency of more than two millimeters was the most frequent finding. Clinical failure was seen in twenty-two (76 per cent) of the twenty-nine cups that loosened early and in nine (28 per cent) of the thirty-two cups that loosened late. The probability of extensive resorption of bone necessitates close observation of patients who have early loosening, while a reasonable period of observation is possible for those who have late loosening.

[An autopsy case of Marfan syndrome with bronchiectasis and multiple bullae].

We report an autopsy case (27-year-old male) with Marfan syndrome, who died of chronic respiratory failure due to bronchiectasis and multiple bullae in both lungs. He had suffered from expectoration of massive amounts of sputum since the age of 15 years. At this time, chest roentgenogram had revealed bronchiectatic changes in the bilateral lower lung fields. Seven years later at the age of 22 years, the formation multiple bullae in both lungs were added to the bronchiectatic changes on chest roentgenogram. Administration of erythromycin (400 mg/day) was started in February, 1987, and the massive sputum volume markedly decreased according to appearance of bullous formation. He was admitted to our department because of deterioration with chronic respiratory failure and right heart failure at 26 years in December, 1989. Although various therapy was performed, he died of chronic respiratory failure in February, 1990. Autopsy findings were as follows: (1) cyclindrical bronchiectatic changes in bilateral lower lobes and (2) extensive multiple bullae in the subpleural areas with bronchiectatic changes in the middle and bilateral lower lobes, with no bronchiectatic changes in the bilateral upper lobes. Several pulmonary disorders accompanying Marfan syndrome have been reported, especially in children. However, the present case demonstrated that fetal pulmonary involvement by Marfan syndrome may not present until adulthood, and affect both airways and lung parenchyma.

[A case of adult pulmonary supravalvular membranous stenosis which was successfully treated by percutaneous transluminal balloon dilatation].

We report a case of adult pulmonary supravalvular stenosis which was successfully treated with percutaneous transluminal balloon dilatation (PTBD). A 42-year-old man was admitted for a heart murmur and abnormal findings in the screening chest roentgenogram. Having no symptoms on admission, his physical activity was evaluated as Class I according to the classification of the New York Heart Association. A systolic murmur (Levine III/VI) with split second sound was audible at the left sternal border in the 3rd intercostal space. Chest roentgenogram revealed 57% of the cardio-thoracic ratio and no signs of increased pulmonary vascular markings. ECG showed incomplete right bundle branch block. Echocardiography and right ventriculography visualized the supravalvular membranous structured stenosed pulmonary artery 1cm above the pulmonic valve. Systolic pressure gradient between the right ventricle and the distal main pulmonary trunk was 54mmHg. The patient was diagnosed as having pulmonary supravalvular membranous stenosis. PTBD was applied using Inoue balloon catheter, where inflation was initiated from approximately 120% of pulmonary arterial diameter and terminated at 150%. This procedure decreased systolic pressure gradient from 54mmHg to 36mmHg without complication. After PTBD right ventriculography demonstrated that a part of the membranous structure had become floppy and movable. Pulmonary arterial diameter was unchanged. We considered that PTBD tore the membranous structure, which consequently resulted in the decrease of systolic pressure gradient. Systolic murmur diminished to Levine II/VI. Six months later, cardiac catheterization showed no change in systolic pressure gradient compared with that immediately after PTBD. This is the first report on pulmonary supravalvular membranous stenosis successfully treated with PTBD.(ABSTRACT TRUNCATED AT 250 WORDS)

[A case of renal cell carcinoma with lung metastasis and local recurrence effectively treated with nephrectomy and UFT].

A 74-year-old woman was admitted on July 18, 1989 for an abnormality on her chest roentgenogram. Right renal tumor with bilateral pulmonary metastasis was detected and right nephrectomy was performed. Because of the progression of pulmonary metastasis and the local recurrence after surgery, UFT was orally administered at a dose of 300 mg everyday since Dec. 12, 1989. The chest roentgenogram on Nov. 21, 1990 showed progression of lung lesions. But at the 20 th month after the beginning of chemotherapy, both lung lesions disappeared completely and local recurrence around the operative wound strikingly improved. This is a rare case of renal cell carcinoma with local recurrence and lung metastasis successfully treated with UFT.

[Indications for radiographic diagnosis in the deciduous molar region].

A total of 4106 children aged 2 to 18 were examined roentgenologically, with intraoral roentgenograms of the molar region being made on 148 (3,6%) of them. Analysis of such roentgenograms allows to make conclusions as to the necessity for making roentgen diagnoses on children.

[Case report of Farmer's lung disease in siblings in Kagoshima Prefecture].

Two cases of farmer's lung disease in siblings are reported. A 54-year-old male farmer, who had been engaged in stock work for 20 years, presented to our clinic for the second episode of fever, productive cough and shortness of breath. Chest roentgenogram revealed diffuse micronodular pattern, and mild hypoxemia was recognized on arterial blood gas analysis. Cytology obtained from BALF showed lymphocytosis, with especially increased OKT3, OKT4 positive cells and OKT4/8 ratio. The diagnosis was confirmed by highly positive reaction of precipitins to Thermoactinomyces vulgaris and granulomatous interstitial pneumonitis on histopathological examination. The second case was a 51-year-old female patient, the sister of the first case, who also worked as a stock farmer of another farm for 20 years. She presented with an episode of similar symptoms to the first case, one and a half years after the onset of her brother's symptoms. The findings of roentgenogram, BALF analysis, precipitins to T. Vulgaris and pathology were similar to those of the first case. The finding of high OKT4/8 ratio on BALF analysis in both cases is characteristic of formers lung disease, in contrast to the summer-type hypersensitivity pneumonitis which usually shows low OKT4/8 ratio in BALF. To our knowledge, this is the first report of farmer's lung disease in an area other than the northern part of Japan. Thus we conclude that farmer's lung disease may occur in Japan under any environmental conditions, and that some genetic factor may take part in the onset of this disease.

[MR imaging of degenerative lumbar disc disease emphasizing on signal intensity changes in vertebral body].

Magnetic resonance imaging was performed in 400 patients with degenerative disc disease. Signal changes and their sites in the vertebral body were classified and referred to narrowing of the intervertebral disc space. MR findings were compared with those of plain roentgenograms of the lumbar spine. Signal changes in the vertebral body were noted in 83 cases (102 vertebral bodies). Low-intensity abnormality on both T1- and T2-weighted images (WI) was the most common finding, and was most frequently seen at the end plate and/or the angle. These changes were correlated with narrowing of the disc space and osteosclerosis on the plain roentgenogram of the lumbar spine. Signal changes occasionally occurred in the inner region of the vertebral body, and these lesions tended to show a high-intensity abnormality on T1-WI. We conclude that signal changes in degenerative disc disease are not specific, but are sometimes difficult to distinguish from the signal changes in other conditions such as spinal tumor or bone marrow disorder.

Stress fracture of the hip. An unusual complication of total knee arthroplasty.

Stress fracture of the hip is a rare complication of total knee arthroplasty (TKA). Only eight cases seem to have been reported in the literature. A ninth case is reported in the present study. A 76-year-old obese woman was treated by right TKA for osteoarthrosis with cementing of the tibial component because of insufficient primary fixation. One year after TKA, she complained of tenderness above the right adductor tendons. There was no history of trauma. One month later, bone scintigrams and roentgenograms demonstrated a stress fracture of the femoral neck. Conservative management was successful. Etiologic factors such as rheumatoid arthritis, osteoporosis, steroid medication, or changes in static or dynamic forces of the hip secondary to knee arthroplasty could not be demonstrated in this patient. The increase in activity after TKA may be a factor in the incidence of these stress fractures of the hip. Radionuclear-type bone scan is helpful in diagnosis. The foci of increased isotope uptake are not always seen at the site of the stress fracture and only later visualized by roentgenograms.

The lateral trochlear sign. Femoral trochlear dysplasia as seen on a lateral view roentgenograph.

Dysplasia of the femoral trochlea is easily detected on an axial roentgenogram of the patellofemoral joint. A roentgenographic sign is described wherein severe trochlear dysplasia can also be readily appreciated on a plain lateral roentgenogram. The subchondral bone of the trochlea is normally seen as a dense white line, which remains parallel to the subchondral bone of the lateral femoral condyle. The intersection of those two lines is indicative of severe trochlear dysplasia and has been named "the lateral trochlear sign."

[A case of isolated absence of the right pulmonary artery].

A 40-year-old woman was admitted to our hospital for investigation of an abnormal chest roentgenogram. She had been well with normal exercise tolerance and had no history of pneumonia. The chest roentgenogram showed decreased vascularity of the right lung, ipsilateral small hemithorax, and shift of the mediastinum toward the right. In the right lung field, hazy and confluent micronodular shadows were seen, and the left lung was emphysematous and hyperlucent. Herniation of the left lung into the contralateral thorax was seen. Although lung perfusion scintigrams showed no detectable blood flow to the right lung, a krypton ventilation study revealed diminished but homogeneous ventilation of the ipsilateral lung. A bronchogram showed normal structure of the bronchi. Cardiac catheterization revealed normal pulmonary arterial pressure. A pulmonary angiogram showed no right pulmonary artery, and absence of other cardiovascular anomalies. Therefore, the diagnosis of isolated absence of the right pulmonary artery was confirmed. An aortic angiogram demonstrated collateral vessels originating from one of the bronchial arteries, the infradiaphragmatic artery, and the right coronary artery. Chest CT disclosed cystic changes in the right lung field.

Perinatal tuberculosis in a three-month-old infant.

Perinatal tuberculosis is a rare disease with a high mortality rate and is difficult to diagnose. We report a case of perinatal tuberculosis diagnosed by postmortem study at the age of 3 months. An 83-day-old male infant presented with cough for 3 weeks and intermittent fever for 1 week. A focal tonic convulsion occurred on the day of admission. Physical examination revealed failure to thrive, tachypnea, and marked hepatosplenomegaly. Chest roentgenogram showed bilateral nodular alveolar-interstitial infiltrates. Abdominal computed tomography showed multiple nodules in the liver and spleen as well as lymphadenopathy in the hepatic portal hilum. Antituberculous therapies were prescribed on the second hospital day. The patient died from respiratory failure on the sixth hospital day. Mycobacterium tuberculosis was cultured from gastric aspirates and cerebrospinal fluid 4 weeks after inoculation. Postmortem examination revealed disseminated necrotizing granulomas in several organs and tissues, including the porta hepatis lymph nodes, a primary hepatic complex. M. tuberculosis infection was diagnosed in his mother based on positive findings of Mautoux test and chest roentgenogram. This case illustrates that tuberculosis, though rare, still should be considered in poor-weight-gain neonates with cough, fever, and/or hepatosplenomegaly. Careful maternal and other family contact history is essential to establishing the diagnosis.

Reevaluation of eosinophilic pneumonia and its diagnostic criteria.

Eosinophilic pneumonia has been defined as pulmonary infiltration of the lung by eosinophils that may or may not be accompanied by an excess of these cells in the peripheral blood. However, the concept of this disease and its nomenclature have not yet been established. In the present study, the clinical course of 11 cases of eosinophilic pneumonia, which were clinico-pathohistologically diagnosed and found not to be associated with organic disorders producing peripheral blood eosinophilia, were investigated extensively and compared with various types of eosinophilic pneumonia, as previously reported. Of five cases of acute eosinophilic pneumonia with a history (less than 1 month) of symptoms before diagnosis, a short clinical course, and no recurrence, four cases showed peripheral blood eosinophilia, and four cases did not require treatment with steroids. Of six cases of chronic eosinophilic pneumonia with a history (greater than 2 months) of symptoms before diagnosis, a prolonged clinical course, and recurrence, all showed peripheral blood eosinophilia, four cases required treatment with steroids, and four cases were recurrent. In one case with simultaneous occurrence of asthma and another case with asthma that occurred 4 years after the appearance of eosinophilic pneumonia, abnormal shadows on chest roentgenograms had continued for several years. These results suggested that various types of previously reported eosinophilic pneumonia classified by sex, the presence or absence of peripheral blood eosinophilia, the degree of clinical symptoms or peripheral blood eosinophilia, and the degree of abnormalities on the chest roentgenograms should be extensively reevaluated.

Radiographic and geometric anatomy of the scapula.

In an effort to study anatomic parameters of the scapula that may be of clinical importance, scapulae were harvested from cadavers and stripped of their soft tissues. For each scapula, three roentgenograms then were obtained: a Y-scapular view, an axillary lateral view, and a glenoid fossa (or true anteroposterior) view. Computed tomographic pneumoarthrograms and randomly selected antero-posterior chest roentgenograms of skeletally mature adults were studied also to measure further roentgenographic parameters of the normal scapula. The geometric anatomy of the scapula is of fundamental importance in the pathomechanics of rotator cuff disease, total shoulder arthroplasty, and recurrent shoulder dislocation. This study presents in detail the exact geometry of scapula anatomy, giving precise figures for distances, angles, and radii of curvature of the scapula. All results then are discussed in terms of their clinical relevance to the above problems.

The accuracy of the Cartier tibial guide in knee arthroplasty.

The authors reviewed, radiologically, the postoperative position of tibial component in 51 knee arthroplasties performed between 1987 and 1989 with Cartier's extramedullary tibial guide. The results compared favourably with those of other studies. A variation of 1.9 degrees on anteroposterior roentgenograms and 2.4 degrees on lateral roentgenograms was obtained by five orthopedic surgeons, suggesting that, for knee arthroplasties, the guide of Cartier is a useful tool and produces reliable results.

[A case of subacute traumatic aneurysm of the thoracic aorta with rare symptom of atelectasis in the left lung].

A case of subacute traumatic aneurysm of the thoracic aorta with atelectasis in the left lung is described. A 17-year-old male was admitted to our hospital because of traumatic shock. Radiographs revealed multiple fractures of upper and lower extremities, but on the chest roentgenogram there was no abnormal finding without slightly widened mediastinum. Next chest roentgenogram, four days later, showed left pleural effusion, atelectasis in the left lung and tracheal shift to the left. By the following examination of CT and DSA, the patient was diagnosed as a traumatic aneurysm at the aortic isthmus. The graft interposition of the descending aorta was performed with help of temporary bypass. He was making satisfactory progress after the operation. Reports about the operation of traumatic aneurysm of the thoracic aorta in subacute phase are relatively rare compared with those in chronic phase. No case, except this case, with tracheal shift to the left because of atelectasis in the left lung has been reported previously in Japan. It must be considered that the trachea may be shifted to the left by atelectasis of the left lung like this case.

Unilateral donor lung dysfunction does not preclude successful contralateral single lung transplantation.

Single lung transplantation remains limited by a severe shortage of suitable donor lungs. Potential lung donors are often deemed unsuitable because accepted criteria (both lungs clear on the chest roentgenogram, arterial oxygen tension greater than 300 mm Hg with an inspired oxygen fraction of 1.0, a positive end-expiratory pressure of 5 cm H2O, and no purulent secretions) do not distinguish between unilateral and bilateral pulmonary disease. Many adequate single lung grafts may be discarded as a result of contralateral aspiration or pulmonary trauma. We have recently used intraoperative unilateral ventilation and perfusion to assess single lung function in potential donors with contralateral lung disease. In the 11-month period ending October 1, 1990, we performed 18 single lung transplants. In four of these cases (22%), the donor chest roentgenogram or bronchoscopic examination demonstrated significant unilateral lung injury. Donor arterial oxygen tension, (inspired oxygen fraction 1.0; positive end-expiratory pressure 5 cm H2O) was below the accepted level in each case (246 +/- 47 mm Hg, mean +/- standard deviation). Through the sternotomy used for multiple organ harvest, the pulmonary artery to the injured lung was clamped. A double-lumen endotracheal tube or endobronchial balloon occlusion catheter was used to permit ventilation of the uninjured lung alone. A second measurement of arterial oxygen tension (inspired oxygen fraction 1.0; positive end-expiratory pressure 5 cm H2O) revealed excellent unilateral lung function in all four cases (499.5 +/- 43 mm Hg; p less than 0.0004). These single lung grafts (three right, one left) were transplanted uneventfully into four recipients (three with pulmonary fibrosis and one with primary pulmonary hypertension). Lung function early after transplantation was adequate in all patients. Two patients were extubated within 24 hours. There were two late deaths, one caused by rejection and Aspergillus infection and the other caused by cytomegalovirus 6 months after transplantation. Two patients are alive and doing well. We conclude that assessment of unilateral lung function in potential lung donors is indicated in selected cases, may be quickly and easily performed, and may significantly increase the availability of single lung grafts.

[A successful surgical treatment of chronic traumatic mid-descending thoracic aortic aneurysm].

A 48-year-old woman with chronic mid-descending thoracic aortic aneurysm was successfully repaired. She received a blunt chest trauma due to automobile accident at July in 1988. Left upper lobectomy was performed for her lung contusion. March 1990, she admitted our hospital with abnormal shadow revealed by a chest roentgenogram. A computed tomogram of the chest and an aortogram revealed two false aneurysms. One of them was located at mid-descending thoracic aorta and another was aortic isthmus. Under a partial femoral veno-arterial bypass, a Dacron graft replacement of mid-descending thoracic aorta was performed and aneurysm of isthmus was wrapped by Teflon mesh after the left pneumonectomy. 2 months after the operation, bronchopulmonary fistula occurred at the left bronchial stump. The fistula was successfully covered with major omentum. The mid-descending thoracic aortic aneurysm due to blunt chest trauma is rare. The traumatic aortic aneurysms commonly occur aortic isthmus or ascending aorta. Initial diagnosis of traumatic mid-descending thoracic aortic aneurysm is often missed or delayed. Careful follow up is need and when an abnormality is revealed by chest roentgenogram, computed tomogram and aortogram should be obtained to make diagnosis of chronic traumatic aneurysm.
