I think the two muscles are medial gastrocnemius and semimembranosus muscle.
The patient undertook non-enhanced MRI before US, and the diagnosis was Baker’s cyst.
Considering the very soft and compressible nature of the mass, the diagnosis of sarcoma is unlikely, but it’s still worth taking enhanced MRI, as you said better be safe than sorry.
Thank you very much, Steve.
