摘　　要：目的：探讨骨内腱鞘囊肿的影像学表现及诊断与鉴别诊断。方法：回顾性分析经手术证实的20例骨内腱鞘囊肿的临床及影像资料,均行X线、CT检查,2例行MRI检查。结果：X线、CT表现为邻近关节面的类圆形囊样透亮区,边界清晰,18例有完整硬化边,10例病灶内见粗细不均的条状骨性间隔,3个病灶通过裂隙与关节腔相通,CT值20～60HU,MRI在T2WI和脂肪抑制序列均表现为高信号。结论：骨内腱鞘囊肿的X线、CT典型表现为骨内邻近关节面的囊状破坏,边界清晰硬化,MRI在T2WI和脂肪抑制序列均表现为高信号,结合发病部位和临床症状及影像学表现,对本病可作出正确诊断。Objective： To analyze the imaging features and differential diagnosis of intraosseous ganglion. Methods： Clinical and imaging features of 20 cases surgically confirmed of intraosseous ganglia were retrospectively analyzed. All of them were examined with X-ray,CT,and 2 cases of them performed MR. Results： Radiographs and CT features included a unilocular cyst surround by a full rim of sclerotic bone in the subchondral epiphysis without any sings of degenerative joint disease. There were integrity linear stiffen edges existed in 18 cases. CT showed an intraosseous ganglion communicating with adjacent joint in 10 cases. CT values of the lesions were between 20～60HU. Intraossous ganglion was seen as low signal on TIWI and high signal on TzWI on MR images. Conclusion： Intraosseous ganglion was typically seen as sharp-margined and cystic lesion on radiographs and CT, MR imaging demonstrated high signal on T2WI and STIR,Combined with lesion distribution,clinical manifestations and imaging features. A suggestion to the diagnosis of intraosseous ganglion could be made.
