title: MR evaluation of giant cell tumors of the tendon sheath.
abstract: Giant cell tumor of the tendon sheath (GCTTS) is a benign condition that involves the synovium of the tendon sheaths. Histologically, GCTTS is similar to pigmented villonodular synovitis. The MRI findings in two cases of GCTTS are reported. In both cases, predominantly low signal is seen on T1-weighted, proton density weighted, and T2-weighted images. This information may be useful in distinguishing GCTTS from other mass lesions involving the tendon sheaths.
