Aneurysmal Bone Cyst with Neurological Involvement in the Spine: Report of Two Cases and Literature Review

Keywords: Aneurysmal bone cyst, thoracic spine, neurological compromise, embolization, spinal surgery, tumor

Abstract

An aneurysmal bone cyst (ABC) is a benign, vascularized bone lesion with an expansile growth pattern. Its presentation with neurological involvement is rare and presents a therapeutic challenge. This article describes two clinical cases of ABC located in the thoracic spine, both with acute neurological compromise. The patients were treated with staged surgical approaches and followed for 24 months. Both achieved complete neurological recovery. Early decompression and spinal stabilization, combined with selective embolization, are highlighted as key components of effective management.
