To investigate the imaging features of synovial tuberculosis of sheath of wrist.
Three patients of synovial tuberculosis of sheath of wrist underwent surgical operation from Oct. 2002 to Oct. 2009 included 2 males and 1 female, the age of 48, 67, 76 years respectivly. X-rays of 3 patients, CTs of 2 patients and MRI of 1 patient were retrospectively analyzed and the relevant literature were reviewed.
There were 3 cases with the soft tissue mass in the palm side of wrist, the section was unclear. There were no osteoporosis and no changes of bone destruction. There was 1 case with the punctate calcification in the soft tissue. MRI showed the embedded cystic mass of flexor tendon and "8" shape in carpal tunnel pressure, and showed abnormal signal (T1 low-signal, T2 slightly higher signal), a small part of the internal point showed high signal. CT showed the synovial membrane were obvious thickening and enhanced, corpus liberum in tendon sheath were no obvious strengthening.
Synovial tuberculosis of sheath of wrist has certain characteristics on radiographic image. The MRI has more clinical value than X-ray and CT.
探讨腕部腱鞘滑膜结核的影像学特征。
回顾性分析2002年10月至2009年10月期间接受手术治疗的3例腕部腱鞘滑膜结核患者的资料，其中男性2例，女性1例，年龄分别为48岁、67岁、76岁。对3例患者的X线、2例患者的CT及1例患者的MRI进行分析，并复习相关文献。
3例患者腕掌侧均见软组织肿块，边界不清。均无骨质疏松及骨质破坏改变。1例软组织内见点状钙化。MRI表现为屈肌腱内局限性囊状肿块，腕管受压呈“8”字形，呈异常信号（T1低信号，T2稍高信号），内部小部分呈高信号。CT表现为滑膜明显增厚、强化，腱鞘内游离体无明显强化。
腕部腱鞘滑膜结核在影像学上有一定特征。MRI较X线及CT有更高的临床应用价值。
