Third ventricle World Health Organization Grade II meningioma presenting with intraventricular hemorrhage and obstructive hydrocephalus: A case report and literature review

BACKGROUND: Third ventricular meningiomas are exceedingly rare intracranial tumors that may present with intraventricular hemorrhage. CASE DESCRIPTION: The patient is 46-year-old who initially presented with obstructive hydrocephalus from a presumed vascular lesion and who was treated with endoscopic third ventriculostomy. He presented 3 years later with acute intraventricular hemorrhage and hydrocephalus. The hemorrhage was evacuated and the third ventricular tumor was resected, and the patient made an excellent recovery. Histopathological analysis identified the tumor as the World Health Organization Grade II meningioma. CONCLUSION: Third ventricular meningioma is a rare tumor that may present with hemorrhage and obstructive hydrocephalus. Surgical resection can be helpful for this rare presentation of intracranial meningioma.
