People mentioned Mazabraud syndrome- Darra from Dublin and Lucas from brazil
I did not think of it as they have myxomas and FD
This one has benign sessile osteochondroma from humerus
plus venous malformation with fluid levels in deltoid
The marrow lesion did not communicate with articular surface or tuberosity cysts. Plus there were oil cysts. Seemed benign- probably from old trauma- so I left as probably benign- OT-RADS III
Here is the impression
Nearly massive rotator cuff tear. Stage III muscle atrophy.
Bone-on-bone degenerative changes of the glenohumeral joint.
Stable osteochondroma of the proximal humerus.
Benign venous malformation of the lateral belly of the deltoid muscle.
Additional focal lesion of the proximal humerus metaphysis appearing complex though with elongated appearance, possibly a benign lesion in view of other oil cysts within the proximal humerus
RECOMMENDATIONS: OT-RADS: III. Probably benign osseous tumor. Recommend surveillance imaging at 3, 6, 12, and 24 months. If the lesion regresses or resolves, surveillance can be terminated if felt clinically appropriate.
