The clinical, angiographic and histological aspects of 20 cases of aneurysmal bone cyst suggest that angiography is a valuable aid in the diagnosis of a cyst, differentiating it from other cystic bone lesions. Angiographic information also has a certain bearing on the origin of the lesion. It was demonstrated that other, benign, lesions may exist adjacent to the cyst or prior to it; in most cases, however, the cyst appears in a bone which is otherwise normal. The failure to differentiate between aneurysmal bone cyst and giant cell tumor in relation to sex, age, localizaiton, morphology, and clinical course (e.g. tendency of recurrence and malignant transformation) may be responsible for confusion in the literature on these lesions. Good results of treatment are achievable by resection en bloc and by resection, or curettage with bone grafting. Curettage alone is inadequate. Only two recurrences (10%) were recorded in the present series during the average follow-up period of 4.5 years.
20例动脉瘤样骨囊肿的临床、血管造影及组织学表现提示，血管造影对囊肿的诊断有重要辅助作用，可将其与其他囊性骨病变相鉴别。血管造影信息对病变的起源也有一定意义。已证实，囊肿周围或之前可能存在其他良性病变；然而，在大多数情况下，囊肿出现在其他方面正常的骨内。在性别、年龄、部位、形态及临床过程（如复发和恶变倾向）方面未能区分动脉瘤样骨囊肿和巨细胞瘤，可能是这些病变的文献中出现混淆的原因。通过整块切除、切除或刮除植骨可取得良好的治疗效果。单纯刮除是不够的。在本系列平均4.5年的随访期内，仅记录到2例复发（10%）。
