Aneurysmal bone cyst: A review of management

Aneurysmal bone cyst is a rare lesion that is most often found in young adults and children. It can have an unpredictable behavior, with a high recurrence rate after treatment. Treatment is based on personal and institutional experience and preferences. Standard treatment consists of curettage (manual + motorized high-speed burr) plus local adjuvants and bone grafting to fill the void. In anatomical locations that are difficult to reach surgically, percutaneous procedures (injection of sclerosant agents, radiofrequency thermal abla-tion (RFTA)) or selective arterial embolization (SAE) are used. Medical management with bisphosphonates (BPs) or denosumab has also been advocated. Minimally invasive surgical procedures such as “curopsy” and percutaneous demineralized bone matrix (DBM) and/or autologous bone marrow concentrate (BMC) grafting.
