Hello all,
I appreciate all the responses we got!
The majority of respondents favored an intramuscular cyst, complex cyst, or hematoma rather than a neoplasm.
We’ll keep you updated if we see follow up with a contrast study or pathology results.
Thanks again,
Elyor

Hello,
I’m an MSK fellow working with Dr. Tirman at Radnet in Los Angeles and we’re curious about the group’s thoughts on the following case.
59 year old man. 9 months of shoulder pain after injury at work. No relevant prior surgery.
The supraspinatus myotendinous junction contains a well-circumscribed lesion demonstrating T1 isointense signal to muscle, intermediate signal on T2, and a rim of low signal; we’re thinking possibly a prior interstitial tear with old hematoma/fibrous tissue, invagination of bursal fluid collection, or soft tissue neoplasm such as a myxoma.We recommended repeating the exam with IV contrast. Any other thoughts would be appreciated!
