Aneurysmal bone cyst, abbreviated ABC, is an osteolytic bone neoplasm characterized by several sponge-like blood or serum filled, generally non-endothelialized spaces of various diameters.[1].The term is a misnomer, as the lesion is neither an aneurysm nor a cyst.[1].   Aneurysmal bone cysts (ABCs) are benign bone lesions arising predominantly in the pediatric population more often in females (2:1), usually before the age of 20 years, and most commonly in long bones metaphysis origin that can cause local pain, swelling, and pathologic fracture. Primary lesions, which constitute roughly two thirds of all ABCs, are thought to be neoplastic in nature due to translocation t(16;17)(q22;p13) leading to juxtaposition of promoter region CDH11 on 16q22, with one third of ABCs arising secondary to other tumors. Diagnosis is made with various imaging modalities, which exhibit characteristic features such as “fluid-fluid levels,” Currently, the standard of care and most widely employed treatment is intralesional curettage and bone grafting .
