目的探讨直接数字化放射摄影术(DR)对手足部腱鞘巨细胞瘤(GCTTS)的诊断价值。方法回顾性分析61例经手术病理证实的手足部GCTTS患者的DR影像资料。DR检查摄手/足正斜位或指/趾正侧位,在工作站上观察手足部GCTTS的影像表现。结果 DR显示所有61例手足部GCTTS的关节旁软组织肿块征象,其中35例(57%)出现骨质压迫、侵蚀及破坏,1例骨破坏同时合并骨膜增生改变,1例软组织肿块内出现点状钙化。结论DR对手足部GCTTS可以起到提示诊断的作用,应作为手足部GCTTS的首选检查方法。
Objective To investigate the diagnostic value of direct digital radiography (DR) on giant cell tumor of tendon sheath (GCTTS) in the foot and foot. Methods Retrospective analysis of 61 cases of pathologically confirmed hand and foot GCTTS DR imaging data. The DR examines the hand / foot tilt or the digit toe position and observes the image of the hand and foot GCTTS on the workstation. RESULTS: DR showed signs of para-soft tissue mass in all 61 cases of hand-foot GCTTS, with osteoporosis, erosion and destruction in 35 cases (57%), periosteal hyperplasia in 1 case with bone destruction, and 1 point in soft tissue mass Calcification. Conclusions GCTTS can be helpful in diagnosing hand and foot GCTTS and should be the first choice of GCTTS in hand and foot.
