RESUMO
PURPOSE: To describe unusual rotator cuff tendon tears which are hyperechoic at ultrasonography (US). MATERIALS AND METHOD: We retrospectively reviewed the shoulder US examinations of 100 patients with rotator cuff tear demonstrated by CT arthrogram with bursography. We included in this study hyperechoic foci without surrounding hypoechoic zone. A second US examination was performed after bursal distension. RESULTS: Six (6%) hyperechoic foci were detected. The initial US diagnosis was tendinosis in five cases (n=5) and full thickness tear in one case (n=1). At repeat US examination, the hyperechoic area was completely or partially hypoechoic, probably because the tears were filled with the injected hypoechoic fluid. CONCLUSION: Some rotator cuff tears, filled with fibrinoid fragments, are probably underdiagnosed at US.

A prospective study of delayed sequences after intravenous injection of gadolinium for knee MRI shows the similar results as from the literature: enhancement of synovial fluid after 30 minutes. Sixteen patients were studied mainly with gradient echo. This phenomenon improves the visualisation of the intraarticular structures like meniscus, cruciate ligaments, or cartilage. This study leads to use this technique in case of difficulties like postoperative intraarticular lesions.

Amebic liver abscess is the most common extraintestinal complication of invasive amebiasis. Amebic abscess is most often located in the right lobe of the liver which is affected four times as often as the left lobe. Location in the caudate lobe is exceptional. We report herein a case of amebic abscess located in the caudate lobe.
