Aneurysmal Bone Cysts

Excerpt

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. Their expansile nature may result in pain and inflammation, and disruption of joints and growth plates. They can grow aggressively, be locally destructive, and weaken bones to the point of pathologic fracture.
