Intramedullary fixation in the proximal femoral diaphysis.
At the middle third of the thigh, deep inside the vastus intermedius, there is a lesion displaying a low signal on T1WI and a high signal on T2WI, that undergoes mild heterogeneous contrast enhancement. The lesion measures 4.8 x 4.7 x 8.1 cm (ml x ap x cc). It violates the cortex and reaches the tip of the intramedullary stem. The lesion's characteristics favour a soft-tissue sarcoma.
The neurovascular structures appear normal.
