Abstract：Objective: To study the imaging features of giant cell tumor of tendon sheath(GCTTS) in the wrist joint to improve our level of understanding the disease. Methods: Seven surgically-and-pathologically-confirmed GCTTS cases were analyzed in the study. Six cases underwent pre-contrast and contrast enhanced CT examinations, 4 patients had MR imaging, one case underwent ultrasonography, two cases underwent bone scanning. Results: CT identified a lobulated mass lesion with destruction of adjacent bones, cross-jointed growth, without calcification and periosteal reaction; heterogeneous enhancement was found on contrast enhanced CT. MRI revealed iso-intensity on T1WI and hyper?蛐hypo-intense on T2WI, which were compared with those skeletal muscle. The masses were markedly heterogeneously enhanced following Gd-DTPA administration. All the lesions were typically related with the adjacent tendon. Conclusion: Some certain characteristics could be found on the imaging of CT and MRI of GCTTS in the wrist joint.
