Spinal aneurysmal bone cysts – case series

Abstract

Aneurysmal bone cysts are benign neoplastic lesions that are extensively vascularized and can occasionally exhibit destructive and expanding activity. They typically affect young people, with a small predilection toward females, and most frequently arise during the second decade of life. Aneurysmal bone cysts account for about 1% of all bone tumors and usually develop in long tubular bones, with the spine being much less commonly affected. We present here three cases of aneurysmal bone cysts in the spinal cord that were surgically treated at the Department of Neurosurgery between 2009 and 2022. These patients were admitted to the clinic with symptoms of spinal cord or vascular compression. The volume of operative intervention was total or subtotal resection of the formation. No postoperative neurological deficits were observed, and no early complications were recorded after the interventions. All patients were discharged from the department with clinical improvement. One underwent reoperation after 4 years because of a cyst recurrence. The diagnosis of aneurysmal bone cyst was confirmed by histological examination in all cases.
