Figure 4.

A 72 year old male with cutaneous angiosarcoma of left lower limb (Case 3). The lesion was surgically resected. ¹⁸F-FDG PET-CT was done 1 year later for suspected local recurrence. Whole body maximum intensity projection (MIP) PET image (a) does not show any distant metastasis. Transaxial CT (b) PET (c) and PET-CT (d) images show ¹⁸F-FDG avid cutaneous thickening in the popliteal region of left leg extending to involve the underlying muscles (arrow). Findings were suggestive of local recurrence and confirmed with biopsy
