Recent Trends in the Management of Aneurysmal Bone Cyst A Systematic Review

Abstract

neurysmal bone cysts (ABCs), were first described by Drs. Jaffe and Lichenstein in 1942 when they described pelvic and spine lesions that when exposing the lesion and opening in to its thin wall, the surgeon was immediately confronted by a large hole containing much fluid blood. The name aneurysmal bone cyst has proven to be a misnomer, however, as these lesions are neither aneurysmal nor truly cystic, as they lack an endothelial wall. Instead, these benign expansile lesions produce cavities within the bone that fill with blood and are lined by proliferative fibroblasts, giant-cells, and trabecular bone. ABCs were historically believed to result from increased venous pressure causing extravasation of cellular and blood contents into cyst-like voids in the bone.
