General Information About Aneurysmal Bone Cyst
Disease Details and Frequently Asked Questions
It is a benign bone tumor consisting of numerous spongy chambers filled with blood within the internal structure of the bone, which rapidly erodes the bone and expands like a balloon, even though it is not a true cancer.
Although the exact cause is not fully known, it is thought to occur due to the vascular structures within the bone showing an abnormal reaction and expanding, along with an increase in intra-bone pressure.
It is usually seen in children and young adults under the age of 20. It occurs most frequently in the long bones around the knee (thigh and shin bones), in the spine, and in the pelvic bone (pelvis).
Severe bone pain in the affected area that gradually increases and continues at rest and at night, a noticeable warm/tender swelling from the outside, and fractures that suddenly occur because the bone is weakened (pathological fracture).
X-ray films show a thinned bone with soap bubble or balloon-like expansion. A contrast MRI is taken to prove the fluid (blood) filled chambers, and a definitive diagnosis is made via biopsy.
The cyst does not heal on its own and surgery is necessary because it makes the bone fragile. In surgery, the inside of the cyst is completely scraped out (curettage), and the remaining microscopic cells are burned with a high-speed burr or phenol. The remaining cavity is filled with bone cement or a bone graft (powder) so the body can repair it, thereby strengthening the bone.
