摘　　要：目的探讨骨内腱鞘囊肿的发病机制、临床特征、影像表现、诊断厦鉴别诊断。方法回顾性分析经病理证实的10例骨内腱鞘囊肿的临床及影像学资料。病灶共14个，其中髋臼5个，舟状骨3个，月骨2个，胫骨近端2个，股骨头1个。结果7例11个病灶X线表现为临近关节面单房性类圆形或不规则形密度减低区，2例2个病灶呈多房性囊状扩张，其内有粗细不等的间隔。其中2例2个病灶与关节腔均见有宽约有1mm相通口。10例14个病灶均显示边缘清楚，有薄层硬化边。结论结合临床症状和影像学表现．对本病可以作出正确的术前诊断。Objective To investigate the pathogenesis, chnical manifestations, imaging features, and differential diagnosis of intraosseous ganglion. Methods Clinical and imaging features of 10cases with intraosseous ganglia were retrospectively analyzed. There were 14lesions, including 5acetabula, 3scaphoid, 2lunate, 2proximal ends of tibia, 2femora head. Results Common radiological features included a unilocular or multilocular cyst surrounded by a full and thin rim of sclerotic bone in the subchondral epiphysis without any signs of degenerative jo.;nt disease. In two cases, the lesion was manifested as muhilocular cystoid expansion with thick or thin septa. 2 cases have 1 mm - wide tubular shadows connecting the cyst to the articular cavity. All the lesions in 10 cases had clear border, with ascleroticmargin. Conclusions Combined with clinical manifestations, it is possible to make a correct diagnosis of intraosseous ganglion.
