Title: Imaging findings of giant cell tumor of tendon sheath(with report of 13 cases)
Abstract: Objective:The X-ray,CT and MRI appearances of giant cell tumor of tendon sheath were analyzed so as to improve the knowledge and diagnostic accuracy of this disease(GCTTS).Methods:The Imaging appearances of 13 cases comfirmed by surgery and pathology were analyized retrospectively.Of the 13 cases,9 were diffuse form and 4 localized form.All the patients were examined by X-ray,4 cases had plain CT and enhanced CT,9 cases were examined by MRI and 6 received contrast enhanced MRI.Results:On X-ray films,only juxta-articular soft tissue mass and bony destruction or erosion could be found.CT scans could provide images better than X-ray films.Soft tissue calcification and liquefaction were found in 1 case.Enhanced scans of the soft tissue mass showed mild to morderate enhancement.Isointensity on T1WI was found in 7 cases.and heterogeneous lower intensity in 2 cases.On T2WI heterogeneous iso-hyperintensity was found in 3 cases,and heterogeneous lower intensity in 6 cases.Enhanced scans showed mild to marked inhomogeneous enhancement in 6 cases.Conclusion:Most of GCTTS can be diagnosed by X-ray film and CT scan.MRI is useful in determining hemosiderin deposition and extent of lesion,especially on enhanced scans.MRI is helpful in raising the diagnosing accuracy rate and plays an important role in the clinical treatment and follow-ups.
