This lesion was surgically resected. At surgery it was pedunculated with frail septae connecting it to the synovium of the posterior popliteal recess of knee.

Histopathology showed islands of dystrophic calcification with some cartilaginous tissue at periphery, a diagnosis consistent with a giant solitary loose body of popliteal fossa. Very few such solitary giant loose bodies have been reported in literature. This one measured 7 x 4.7 x 6 cm.
