Locations of lesser tuberosity cysts and their association with subscapularis, supraspinatus, and XXXX disorders.

BACKGROUND: Humeral head cysts are not uncommon in individuals with rotator cuff disorders. The cysts are usually considered an indicator of rotator cuff pathologies; however, they may have different meanings in different regions. PURPOSE: To determine the frequency of cysts within and adjacent to the lesser tuberosity and the relationship between these cysts and subscapularis, supraspinatus, and long @entity135 . MATERIAL AND METHODS: We retrospectively reviewed 760 consecutive shoulder magnetic resonance imaging (MRI) examinations. Among these MRIs, we selected a group of @entity1 with cysts located around the lesser tuberosity. The study population was also divided into two subgroups, @entity1 with @entity2916 and those with cysts adjacent to the lesser tuberosity. In addition to the number and size of cysts, the MRI appearance of the tendons was evaluated. RESULTS: Eighty-one (10.7%) @entity1 had cysts within and/or adjacent to the lesser tuberosity, 34 (42%) @entity1 had @entity2916 , and 47 (58%) @entity1 had cysts adjacent to it. @entity135 and @entity74 were significantly related to more than one cyst. In a univariate analysis, @entity2916 were significantly associated with @entity135 and @entity74 ; however, multivariate analyses showed that only @entity135 were significantly associated with @entity2916 . CONCLUSION: Cysts within the lesser tuberosity were less common than cysts adjacent to it. @entity135 and @entity74 were more frequently found in @entity1 with more than one cyst within and/or adjacent to the lesser tuberosity. In addition, @entity2916 were associated with @entity135 .
