title: Semimembranosus ganglion cyst.
abstract: Ganglion cysts are tumor-like lesions in the soft tissues, generated by mucoid degeneration of the joint capsule, tendon or tendon sheaths on the dorsum of hand, wrist and foot. However, an intratendinous origin for a ganglion cyst is extremely rare. During dissection of the popliteal fossa, a cyst of 2.5 cm×2 cm×0.5 cm was observed in the tendon of right semimembranosus, 3.5 cm above the insertion of the muscle. Contrast X-ray revealed the cyst as not communicating with the knee joint or any adjacent bursae. Histopathological examination confirmed the diagnosis of ganglion cyst.
