Left thigh mass Note that evaluation of the femur is limited by the presence of an intramedullary rod which affixes a fracture of the femoral diaphysis. Within the vastus medialis approximately 17 cm from the femoral head is a well-circumscribed mass measuring 4.5 x 3.7 x 4.7 cm in the greatest transaxial and craniocaudal dimensions. The mass demonstrates slightly hypointense signal on T1 sequences and heterogeneously hyperintense signal on T2 sequences. It approaches the cortex of the femur but the plane between the mass and bone appears preserved. Following contrast administration, the mass enhances demonstrates fairly solid homogeneous enhancement. No additional abnormal enhancement is identified.
Solid intramuscular mass of the thigh suspicious for recurrent malignancy.
