Tenography in unresolved ankle tenosynovitis.

Tenosynovitis can be a source of prolonged ankle pain and disability. Based on a review of the literature and past clinical experience at our institution, early establishment of the correct diagnosis enabling definitive treatment may be difficult. We describe six patients with tenosynovitis of tendons about the ankle, the value of tenography in staging the severity of their disease, and its value in choosing appropriate definitive therapy.

Carpal avascular necrosis: MR imaging.

The authors evaluated the use of magnetic resonance (MR) imaging in diagnosis of avascular necrosis (AVN) of carpal bones by examining 21 patients with wrist pain and two healthy volunteers. MR images were compared with conventional radiographs in every case and with bone scintigrams in 18 cases. MR imaging was slightly less sensitive than bone scintigraphy in depicting AVN, but in patients who were imaged with long repetition time (TR)/long echo time (TE) sequences in addition to short TR/short TE sequences, MR imaging was found to be more specific. While the authors believe that bone scintigraphy remains the screening test of choice for patients with wrist pain and normal plain radiographs, MR imaging promises to add significant diagnostic information in cases in which bone scans are abnormal.

Duplication of the inferior vena cava in thromboembolic disease.

Recurrent pulmonary embolism from the lower extremities or pelvis, despite anticoagulation, often requires interruption of the inferior vena cava (IVC). We report two patients in whom interruption of the IVC failed to ameliorate symptoms. Both patients demonstrated a previously unrecognized duplication of the IVC. We stress the importance of excluding abdominal venous anomalies prior to interrupting the IVC using surgical or percutaneous methods.

Pitfalls of rotator cuff sonography.

Experience with rotator cuff sonography in 106 patients was analyzed to identify the causes of scan misinterpretation. Possible interpretive errors may be classified into four categories: those from failure to recognize normal anatomy, those caused by soft-tissue abnormalities, those caused by bony abnormalities, and those caused by technical limitations of the study. Errors in recognition of normal anatomy are easily overcome by experience and comparison to the normal, contralateral rotator cuff. Errors resulting from soft-tissue abnormalities were seen in two patients with calcific tendinitis simulating rotator cuff tears. Problems in interpretation resulting from fractures in two patients and inferior glenohumeral subluxation in two other patients could have been avoided by review of the plain films before performing sonography. The major technical limitation of the study arises from the inability to image the rotator cuff beneath the acromion. Fortunately, rotator cuff tears are rarely isolated in this location, and passive maneuvers often allow otherwise hidden parts of the cuff to be imaged.

Ultrasonographic evaluation of the rotator cuff and biceps tendon.

Ultrasonography of the rotator cuff and biceps tendon was investigated in 106 patients who had been referred for arthrography of the shoulder. Both the sensitivity and the specificity of ultrasound in detecting a tear of the rotator cuff were 91 per cent. The predictive value of a negative sonogram was 95 per cent and the predictive value of a positive sonogram was 84 per cent. Ultrasonography proved to be superior to arthrography in the examination of the normal and abnormal biceps tendon. Sonographically detectable effusions from the tendon sheath of the biceps were present in 19 per cent of this population of patients. This finding was statistically highly associated (90 per cent) with rotator cuff tears and other soft-tissue abnormalities of the shoulder. Based on these results, it appears that ultrasonography can be used as the initial imaging test for many patients with suspected abnormalities of the rotator cuff or biceps tendon.

Histiocytic reaction to hip arthroplasty.

Pain secondary to loosening of a total hip prosthesis is a common complaint and a major complication after surgery. Periprosthetic lucency is a well-recognized result of loosening of the prosthesis and of infection. We describe histiocytic proliferation as an additional cause of periprosthetic lucency and lytic change in two patients. To our knowledge, this has not been previously reported in the radiological literature.

US of the biceps tendon apparatus.

High-resolution real-time sonography of the biceps tendon was performed on 80 patients referred for shoulder arthrography. The arthrograms and sonograms were compared at the levels of the biceps tendon groove and distal tendon. Sonography and arthrography were equally successful in facilitating the evaluation of the bony configuration of the biceps tendon groove, but sonography gave a superior image of the biceps tendon within the groove. In 16 patients, biceps tendon sheath effusions or swelling was detected using sonography; 15 of these patients had associated pathologic conditions elsewhere in the joint. Arthrograms did not disclose a biceps tendon or sheath abnormality in any of these patients. We conclude that sonography could be the imaging method of choice in patients with suspected biceps tendon lesions and that the presence of a biceps tendon or sheath abnormality indicates an increased likelihood of abnormalities elsewhere in the joint.

Ewing's sarcoma in bones of the hands and feet: a clinicopathologic study and review of the literature.

Review of current data from the Intergroup Ewing's Sarcoma Study (IESS) shows that Ewing's sarcoma (ES) is rare in bones of the hands and feet. Only 12 of 377 evaluable patients in the first two IESS studies had a primary tumor in these small, distal bones. The age distribution was typical for that seen in patients with ES at other sites. Males were affected twice as often as females, and tumors in the bones of the feet were much more common than those in the hands. All signs and symptoms were local in distribution. As in other sites, the dominant histologic pattern was categorized as diffuse. With the exception of those patients with lesions in the calcaneus, the prognosis for disease-free survival was excellent. A literature review of cases of ES reported in bones of the hands and feet showed generally comparable results.

Radiographic appearance of Ewing sarcoma of the hands and feet: report from the Intergroup Ewing Sarcoma Study.

Review of current data from the Intergroup Ewing Sarcoma Study (IESS) shows that Ewing sarcoma is rare in bones of the hands and feet. The 12 patients from the IESS protocols with hand or foot Ewing sarcoma are comparable to those already reported in the literature. With the exception of lesions in the calcaneus, the prognosis for disease-free survival is excellent. The radiographic features of hand and foot Ewing sarcoma are generally those of classic Ewing sarcoma: permeation, soft-tissue mass, and, often, associated sclerotic reaction. However, with the exception of sclerosis, features suggesting bone reaction and slow tumor growth in these patients were distinctly uncommon compared with Ewing sarcoma in general. Those radiographic features suggesting aggressive behavior were slightly more common than in the general Ewing population. Even so, neither the radiographic appearance nor the greatest dimension of the radiographic lesion can be shown to contribute significantly to prognostication in these patients. Apparently location of the lesion is important, since in the reported cases in the literature and in this series, lesions of the calcaneus fared poorly. The importance of this set of patients therefore relates to awareness and early recognition of an unusual appearance and location of Ewing sarcoma.

Sonographic detection of rotator cuff tears.

Thirty-nine consecutive patients referred for shoulder arthrography underwent shoulder sonography to determine the ability of sonography to detect rotator cuff tears. Fifteen patients had arthrographically proven rotator cuff tears. Of these, 14 were detected by sonography, for a sensitivity of 93%. The three sonographic criteria indicative of rotator cuff tear were (1) discontinuity in the normal homogeneous echogenicity of the rotator cuff; (2) replacement of the normal homogeneous echogenicity by a central echogenic band; and (3) nonvisualization of the cuff. Twenty patients had normal sonographic examinations, 19 of which were normal by arthrography. Therefore, the predictive value of a negative sonogram was 95%. On the basis of these findings, sonography can provide a noninvasive means of screening patients with suspected rotator cuff tears.

Hexabrix as a contrast agent for ascending leg phlebography.

Fifty patients were analyzed after a randomized double-blind study comparing Hexabrix and Hexabrix-20 in ascending phlebography. Measures of safety and patient tolerance indicated that both concentrations of Hexabrix appeared safe and were well tolerated. All studies were diagnostic, and the image quality was rated as excellent in 80% of the Hexabrix group and 72% of the Hexabrix-20 group. The authors conclude that Hexabrix and Hexabrix-20 are acceptable contrast media for ascending phlebography.
