Aneurysmal bone cyst, right shoulder
Clinical Classification Guidelines
Medical Intelligence & Overview
An aneurysmal bone cyst (ABC) is a benign, blood-filled bone lesion that causes the bones to weaken and swell. When it develops in the right shoulder, it involves the upper arm bone (humerus) or the shoulder blade (scapula). Despite its name, an aneurysmal bone cyst is not a true cyst but a space filled with blood and tissue within the bone. Though it is considered benign, ABCs can grow rapidly and cause structural damage to the affected bone, leading to pain, swelling, and potential fractures if left untreated.
