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.
