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

Abstract

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.

Primary central nervous system lymphoma of the third ventricle with intra‑tumoral hemorrhage: A case report and literature review

“…PCNSL with ITH reveals overexpression of vascular endothelial growth factor (VEGF), and progression of angiogenesis and breakdown of fragile vessels may cause ITH ( 13 , 32 ). Meanwhile, in specific intraventricular tumors, angiomatous lesions and abnormalities of the draining vein, such as venostasis and venous thrombosis in the subependymal layer arising from tumor extension may lead to ITH ( 14 , 33 , 34 ). In addition, a significant change in ICP may alter a cause of ITH in intraventricular tumors ( 35 ).…”

“…Conversely, ITH in PCNSL is extremely rare, the presence of ITH is even used to exclude PCNSL from the differential diagnosis (13). According previous report, 6.25% of the lateral ventricle tumors present with intraventricular bleeding, however, only a few cases of the ventricle tumors presenting ITH have been described (14)(15)(16). Moreover, no cases of third ventricle PCNSL presenting with ITH have not been reported previously.…”
