| Abstract: | OBJECTIVE: This study was designed to explore the relationship between intramuscular cysts and rotator cuff tendon tears. CONCLUSION: Intramuscular cysts are strongly associated with rotator cuff tendon tears. Identification of such a cyst should prompt a search for a rotator cuff tear. Findings on MR arthrography and surgery suggest that a delaminating component of the rotator cuff tear may lead to the development of these cysts and may explain the occasional discrepancy between location of tears and location of cysts. |
