Giant cell tumors of the synovial sheaths (GCTSS), or tenosynovial giant cell tumor, or hemopigmented villonodular synovitis, develop from the articular and periarticular synovium. LVPS may be clinically indistinguishable from meniscal injury or other internal disturbance. This lesion is histologically identical to its diffuse counterpart but has a different behavior and response to treatment. MRI usually reveals a variable-sized of nodule with a decreasing heterogeneous signal on T1-weighted and T2-weighted images.In arthroscopy; there is a slightly Giant cell tumors of the synovial sheaths (GCTSS), or tenosynovial giant cell tumor, or hemopigmented villonodular synovitis, develop from the articular and periarticular synovium.
