Radiographic chest abnormalities in adult hemophilia.

The chest radiographs of 33 adult hemophiliacs were reviewed for possible pulmonary features of this disease. Only 7 patients showed no abnormalities; 12 patients exhibited scarring, fibrosis, and pleural thickening of the lung, interpreted as the sequelae of intrapulmonary hemorrhage or hemothorax. The remaining 14 patients demonstrated abnormalities of the pulmonary vessels, and 4 of them had evidence of hyperinflation. Possible etiologic factors are discussed.

Post-traumatic pneumatocele in the inferior pulmonary ligament.

Pneumatocele localized to the inferior pulmonary ligament is an uncommon sequel of blunt chest trauma. Three such cases are reported and the characteristic location and appearance of the pneumatocele, as well as its benign course, are discussed. A similar radiographic appearance has been produced in cadavers by injecting air into the inferior pulmonary ligament.

Thickening of the posterior tracheal stripe: a sign of squamous cell carcinoma of the esophagus.

A thickened posterior tracheal stripe (wider than 4.5 mm) was identified on the lateral check radiographs of 20 patients with squamous cell carcinoma of the esophagus. Autopsy studies confirmed that peri-esophageal lymphatic involvement was responsible for the thickening of the stripe in the nonobstructed esophagus. This sign appeared on the lateral chest radiograph as early as 6 months prior to the development of symptoms in 50% of the cases studied.

Hazards of the intensive care unit.

Complications arise in the introduction, maintenance, and use of devices for life support and monitoring in an intensive care unit. Since recognition of such complications is frequently difficult in this clinical setting, the radiologist is often in a position to be the first to detect complications associated with the use of endotracheal and tracheostomy tubes, Swan-Ganz catheters, subclavian catheters, central venous pressure catheters, and intra-aortic balloons.

Hemophilic pseudotumor. Diagnosis, treatment, and complications.

Patients with hemophilia are living longer as a result of improved therapeutic measures. Associated with this longevity is the increased occurrence of complications affecting the osseous system. One of the more serious bone complications is the hemophilic pseudotumor or hemophilic cyst. We studied its diagnosis, treatment, and complications, and report a case of an early hemophilic cyst occurring in a new location, the proximal part of the left clavicle. The increased incidence of this complication should alert the clinician to the possibility of these lesions appearing in previously unreported sites and demonstrating atypical roentgenographic features. Early recognition and treatment is essential if optimal therapeutic results are to be obtained.

Thymoma and systemic lupus erythematosus.

The simultaneous occurrence of a thymoma and systemic lupus erythematosus (SLE) is reported. Disease state associated with thymoma are reviewed and the possible immunological basis for this spectrum of diseases is discussed. The role of angiography in the diagnosis of thymic tumours is described.

Radiology of the Swan-Ganz catheter and associated pulmonary complications.

Radiographic features of the Swan-Ganz catheter and the complications associated with its use are described. Pulmonary infarcts develop subsequent to wedging of the catheter in a peripheral position, failure to deflate the balloon after use, and maintenance for morethan 72 hours. The radiology of the infarct is usually classical in appearance, i.e., pleural-based density which resolves in 14-21 days. The frequency of pulmonary ischemia may BE related to compromise of the venous and collateral arterial circulation in intensive care unit patients in whom the catheter is used.

Traumatic disruption of the thoracic aorta: significance of the left apical extrapleural cap.

The plain chest film may be critical in deciding whether a seriously injured patient should undergo aortography in order to exclude traumatic aortic rupture. The roentgen findings suggestive of aortic transection reflect the presence of mediastinal bleeding. A left apical extrapleural cap is frequently seen in these patients but heretofore has not been emphasized in the literature.

The prevalence of mycoplasmal complement-fixing antibodies in sarcoidosis.

Complement-fixing antibody titers to Mycoplasama pnuemoniae were measured in the sera of 31 patients with sarcoidosis and 31 control subjects matched by age, sex, and race. Data indicated a binomial distribution and a geometric mean titer of 1:32 in patients with sarcoidosis. In contrast, the control data were skewed,with a geometric mean titer of less than 1:8. Possible explanations include generalized increase in antibody formation, unusual susceptibility to infection with M.pneumoniae, and sarcoidosis as one consquence of infection with M.pneumoniae.

Drowning: another plunge.

Hypoxia, pulmonary edema, acidosis, and aspiration compose the syndrome of near drowning. A review of 20 cases of near drowning indicated that the initial chest roentgenogram bears little weight in assessing the present or future clinical status. In some cases a 24 to 48 hour delay occurred before roentgenographic evidence for pulmonary edema was noted. The composition of fluid aspirated does not affect the outcome. The results of this report suggest that patients with a history of near drowning should be followed closely for at least 48 hours despite an initial normal chest roentgenogram.

Critical review of tomography in radiology and nuclear medicine.

This review covers conventional radiographic tomography, radioisotopic tomography, and a review of computerized transaxial tomography. Simple, reproducible radiographic tomographic methods are increasing in use, and despite their complexity, the diagnostic results are superior to conventional radiographs. There are many different motions of the X-ray tube and the film which can be employed to create a tomogram. The perfect tomographic motion is partly determined by the geometric shape of the object to be imaged and the thickness of the plane of interest. The undirectional tomographic method blurs a point in a linear fashion; the pleuridirectional method blurs a point over a wider surface. Among the most popular directions used are linear, circular, elliptical, and hypocycloidal. The numerous applications of tomography described in this review are an encouraging, broad-based foundation from which the most clinically useful and economically feasible devices will emerge.
