【摘要】 本文报告4例继发于骨巨细胞瘤的动脉瘤样骨囊肿.患者年龄28～46岁(平均40岁).病变位于干骺端和骨端,X线表现为膨胀性、溶骨性破坏.1例见骨膜反应,1例有软组织肿块.组织学上,除动脉瘤样骨囊肿外,尚有典型的骨巨细胞成分,两者间有移行关系.4例囊腔内血压均显著升高,术中失血量大.2例载肢.另2例行搔刮和植骨术,2.5—3年后X线复查见植骨片已被溶解吸收.此启示单纯搔刮和植骨不适用于治疗继发性动脉瘤样骨囊肿.更多还原

【Abstract】 4 cases of the aneurysmal bone cyst secondary to giant Cell tumour are presented. The ages range from 28 to 46 (mean 40 years): Roentgenograms showed expansile and osteolytic destruction On metaphysis and epiphysis, in which there were some coarse septation In one of the cases was found periosteal reaction and soft tissue mass in another. Histologically, in addition to the aneurysmal. bone cyst the eases were found in association with the typical pattern of the giant Cell tumour of bone. All the cases appeared elevation in blood pressure in the cyst cavity.The massive hemorrhage occurred on operation. Two cases underwent amputation and the others were trealed with curetiage and bone graft. 2.5. to 3 years later, the graft was absorbed on roentgenograms. It is suggested that the secondary aneurysmal bone cyst does not respond to simple curettage and grafting.更多还原
