Magnetic resonance imaging of the tumors. (A) A T2-weighted coronal magnetic resonance imaging scan showed two soft-tissue tumors in the intramuscular layer between the vastus medialis muscle and the adductor muscle. Extensive peritumoral inflammatory edema was obvious. (B) A T1-weighted axial magnetic resonance imaging scan of the distal tumor (size, 4.0 × 4.0 × 3.5cm) showed homogeneous low signal intensity. (C) A T2-weighted axial magnetic resonance imaging scan showed heterogeneous low and high combined intensities.
