Aneurysmal bone cyst (ABC) is a solitary, expansile and erosive lesion of bone. It is found most commonly during the second decade and the ratio of female to male is 2:1. ABC's can be found in any bone in the body. The most common location is the metaphysis of the lower extremity long bones, more so than the upper extremity. The vertebral bodies or arches of the spine also may be involved.Approximately one-half of lesions in flat bones occur in the pelvis. One theory of the etiology of primary ABCs is that these lesions are secondary to increased venous pressure that leads to hemorrhage which causes osteolysis. This osteolysis can in turn promote more hemorrhage causing amplification of the cyst. Bonetumor.org

Introduction Differentials Radiograph CT Scan MRI Ultrasound Nuclear Medicine Angiography Intervention Bibliography Background: An aneurysmal bone cyst is an expansile osteolytic lesion with a thin wall, containing blood-filled cystic cavities. The term aneurysmal is derived from its radiographic appearance. Pathophysiology: Trauma is considered an initiating factor in the pathogenesis of some cysts in well-documented cases involving acute fracture. Local hemodynamic alterations related to venous obstruction or arteriovenous fistulae that occur after an injury are important in the pathogenesis of an aneurysmal bone cyst.

The aneurysmal bone cyst (ABC) is an expansile cystic lesion that most often affects individuals during their second decade of life and may occur in any bone in the body. Although benign, the ABC can be locally aggressive and can cause extensive weakening of the bony structure and impinge on the surrounding tissues. The true etiology and pathophysiology remain a mystery, but the mainstay of treatment has been intralesional curettage. Recurrence is not uncommon. Other surgical options include en bloc resection or wide excision, selective arterial embolization, and curettage with locally applied adjuvants such as liquid nitrogen or phenol.
