Aneurysmal Bone Cysts

Aneurysmal bone cysts are non-malignant, tumor-like, vascular lesions comprised of blood-filled channels. Although they can occur in any bone, they are most common in the femur, tibia, and vertebrae.[1] Their expansile nature may result in pain and inflammation, disrupting joints, and growth plates. They can grow aggressively, be locally destructive, and weaken bones to the point of pathologic fracture.
