Causes and Risk Factors. These cysts usually occur without any known cause. They affect people who are 20 or younger. Diagnosis. The cyst may be present for a few weeks to a Aneurysmal bone cysts (ABCs) are benign (not cancerous) lesions in bone, also called benign bone tumors. Although ABCs are not cancer, they can be very destructive to Aneurysmal bone cysts can be classified by whether they develop alone (primary) or along with another type of bone tumor (secondary). About 1 in 3 aneurysmal bone cysts are Aneurysmal bone cysts (ABC) are benign but locally aggressive lesions. The treatment of ABC has evolved over the years, but curettage with or without local adjuvants still represents the standard. Less invasive methods such as embolization, sclerotherapy or RANKL inhibitors (Denosumab) are also established The Espada (十刃 エスパーダ, Esupāda; Spanish for " Sword ", Japanese for " Ten Blades ") are the ten top-ranked and most powerful Arrancar in Sōsuke Aizen 's army of Hollows Aneurysmal bone cysts (ABCs) are blood-filled, locally destructive, benign cystic bone tumors that account for about % of all primary bone tumors. 1 They 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, and disruption of joints and growth plates Radiographs demonstrate a sharply defined, expansile solitary lucent bone lesion, with thin-walled cavities 3.
