Aneurysm of the Posterior Meningeal Artery Embedded Within a Dorsal Exophytic Medullary Hemangioblastoma: Surgical Management and Review of Literature

ABSTRACT

Hemangioblastomas are World Health Organization (WHO) Grade I neoplasms of the hindbrain and spinal cord, whose management can be complicated by preoperative hemorrhage. We report on a case of a young female in extremis with posterior fossa hemorrhage following rupture of a fusiform posterior meningeal artery aneurysm embedded within a medullary hemangioblastoma. We discuss management options, including operative staging and embolization, and review similar cases of hemangioblastoma associated with aneurysm.
