The most recent images identified a 20 mm soft tissue lesion located just above the right popliteal fossa, between the muscles in the deep posterior compartment and the distal shaft of the femur (Fig. 2).
Standard soft tissue tumour protocol MRI of the right knee showing a 16 x 17 x 19 mm soft tissue lesion. It is of intermediate signal intensity on T1-weighted, mixed high signal intensity on fluid sensitive sequences and shows moderate enhancement post contrast administration. The lesion is marked in red and lies anteromedial to the popliteal artery.
