动脉瘤样骨囊肿10例分析

Aneurysmal Bone Cyst—A Report of 10 Cases

本文对10例动脉瘤样骨囊肿进行分析,指出本症X线表现差异大,术前误诊率高。10例均属原发型。6例曾行诊断性穿刺,均见静脉样血液涌出,表明囊内压高,间接支持此症可能是骨内动、静脉异常引起静脉高压,导致骨质广泛破坏性病变的发病机理推断。不彻底的刮除术复发率可达30.5％～58％。本组6例采用刮除后囊腔壁95％酒精灭活处理,无一例复发。

Clinically, aneurysmal bone cysts are not rare,but easily misdiagnosed before operation. Part of such lesion may coexist with bone tumors or tumorous conditions, so the specimen of every aneurysmal bone cyst case should be examined carefully to rule out the possibility of the existence of concomitant lesions. Diagnostic punctures were performed in 6 of our cases, and venous-like blood spurted out immediately, indicating high pressure inside the cysts, this indirectly supported the view that the pathogenesis of aneurysmal bone cyst probably was resulted from a local change in hemodynamic, leading to the marked increase of venous pressure and the development of a dilated and engorged vascular bed witbin the affected bone area. The recurrence rate of curettage is high.The paper preferred using 95% alcohol to devitalize the cyst after curettage as to decrease recurrene.
