Aneurysmal bone cyst
Aneurysmal Bone Cyst
Aneurysmal bone cyst (pronunciation: an-yuh-riz-muhl bone sist, from Greek aneurysma, "dilation" + kystis, "bladder") is a benign, non-neoplastic, vascular lesion that arises in the bone. It is characterized by several sponge-like blood or serum-filled, generally non-encapsulated cystic spaces.
Definition
An Aneurysmal bone cyst is a rare, benign, locally destructive lesion of the bones. It is characterized by the presence of large, blood-filled spaces separated by fibrous septa. These septa may contain osteoclast-like giant cells and reactive woven bone.
Etiology
The exact cause of aneurysmal bone cysts is unknown. However, they are often associated with other benign bone lesions such as fibrous dysplasia and giant cell tumor of bone.
Symptoms
Patients with aneurysmal bone cysts often present with pain, swelling, and a palpable mass. Pathologic fracture may occur in some cases.
Diagnosis
Diagnosis of aneurysmal bone cysts is typically made through a combination of clinical history, physical examination, radiographic imaging, and histopathologic evaluation.
Treatment
Treatment options for aneurysmal bone cysts include surgical curettage, radiotherapy, embolization, and sclerotherapy. The choice of treatment depends on the location and size of the cyst, as well as the patient's age and overall health.
Prognosis
The prognosis for patients with aneurysmal bone cysts is generally good, especially when the lesion is completely removed. However, recurrence can occur, especially in cases where complete removal is not possible.
