The symptoms of an aneurysmal bone cyst typically begin with pain. This cyst can weaken the bone over time, leading to pain due to structural insufficiency. Initially, the pain may be mild and overlooked, but it can become more pronounced and continuous as the thinning of the bone progresses or when a non-traumatic (pathological) fracture occurs. At this point, it is crucial to accurately differentiate whether the resulting fracture is a simple traumatic fracture or a pathological fracture developing due to an underlying cyst. The treatment approach for pathological fractures will differ from that for traumatic fractures.
