Aneurysmal bone cysts rather than local aggressive lesions of the bone which may arise in any part of the axial or appendicular skeleton. Although several theories are available in the literature, the pathogenesis is still conflicting. We report an exceptional case of an aneurysmal bone cyst in the distal femur of a female cerebral palsy patient who underwent bilateral distal femoral derotational osteotomy and plate-screw fixation operations when she was 11 years old. Twenty-four months after the operation, radiographs showed a cystic lesion in the distal portion of the right femur around the osteotomy site. The diagnosis of Aneurysmal Bone Cyst (ABC) was made and the lesion was treated by curettage with cement application. After 36 months of follow-up, there was no recurrence. This is the first case reported in literature which raises the possibility that an osteotomy could be a cause in the development of an aneurysmal bone cyst.
骨动脉瘤样囊肿而非可能出现在中轴或附肢骨骼任何部位的局部侵袭性骨病变。尽管文献中有几种理论，但发病机制仍存在争议。我们报告了一例特殊病例，一名女性脑瘫患者的股骨远端出现骨动脉瘤样囊肿，她11岁时接受了双侧股骨远端旋转截骨术及钢板螺钉固定手术。术后24个月，X线片显示右股骨远端截骨部位周围有一个囊性病变。诊断为骨动脉瘤样囊肿（ABC），并通过刮除加骨水泥填充进行治疗。随访36个月后，无复发。这是文献中报道的首例病例，提示截骨术可能是骨动脉瘤样囊肿发生的一个原因。
