  Fig. 3. 1.5-T MRI (a: contrast-enhanced T1-weighted image with fat suppression in axial view of the thigh; b: Contrast-enhanced T1-weighted image with fat suppression in axial view of the groin; c: Proton density weighted image with fat suppression in coronal view of the thigh). a shows a small nodular recurrence with slight edema (white arrowhead). b presents an ovoid/nodular recurrence (white arrow), which can easily be misinterpreted as a lymph node. c shows a multilobulated recurrence (black arrow) with adjacent edema
