A bulbo medullary hemangioblastoma revealed by hemorrhage: A case report

Introduction: Hemangioblastomas are highly vascularized tumors of unclear origin. Most hemangioblastomas arise in the posterior fossa. Although spontaneous hemorrhage from these tumors is extremely rare, despite their vascular nature, we describe a case of a bulbo- medullary hemangioblastoma revealed by hemorrhage. Case report: This is a 12-year-old child, with no past-history, presented with a picture of subarachnoid hemorrhage (sudden, intense, thunderclap headaches associated with vomiting and stiff neck, for which the Neuroradiological investigation was in favor of a bulbo-medullary lesion which infracentimetric lesion was found, with anapath was in favor of a hemangioblastoma. Conclusion: Hemangioblastomas are rare tumors that can be revealed by hemorrhage. Imagery can be misleading. In the case with very small lesion, careful neurovascular appraoch is recommended.
