Figure 1: (a) Maximum intensity projection image showing hypermetabolic lesion in the right hip region (yellow arrow). (b and c) Axial and coronal positron emission tomography, fused and computed tomography images of the right hip joint region showing a pedunculated lesion with areas of cystic and soft tissue component in the soft tissue (yellow arrow), (d) Collections of foamy and pigment laden macrophages, along with fibroblasts (H and E, ×100). Inset (top left corner, ×20) shows low power view of nodular spaces lined by giant cells findings characteristic of pigmented villonodular synovitis
