Background:
Meningiomas are the most common benign intracranial tumors, and commonly comprise high-vascularizing but slow-growing tumors. On the other hand, meningiomas arising from the ventricular system are of rare occurrence, and spontaneous hemorrhage is an infrequent event.
Case Presentation:
We describe here the rare clinical manifestations of a 28-year-old female with acute intracranial hemorrhage located in the trigone of the lateral ventricle who was initially thought to have suffered an acute cerebrovascular accident, but was subsequently confirmed to have a benign intraventricular meningioma. To clarify the clinical features of such a rare course of meningioma, we also present a short literature review of acute intracranial hemorrhage caused by intraventricular meningioma.
Conclusions:
Ventricular meningioma presenting with hemorrhage such as acute stroke is a rare event, but recognition of such a pathogenesis is important. Although further accumulation of clinical data is needed, we suggest that early surgery should be undertaken in patients with lateral ventricular meningioma, even if it is not so large or asymptomatic.
Insights
Intraventricular meningiomas are rare tumors that can cause sudden intracranial hemorrhage, mimicking a stroke. Early surgical intervention is recommended for lateral ventricular meningiomas, even if asymptomatic, to prevent such complications.
Area of Science:
- Neurology
- Neurosurgery
- Oncology
Background:
- Meningiomas are common benign intracranial tumors, typically slow-growing.
- Intraventricular meningiomas are rare, with spontaneous hemorrhage being an infrequent occurrence.
Observation:
- A 28-year-old female presented with acute intracranial hemorrhage in the lateral ventricle trigone.
- Initial diagnosis was acute cerebrovascular accident, later revised to benign intraventricular meningioma.
Findings:
- This case highlights the rare presentation of intraventricular meningioma causing acute intracranial hemorrhage.
- Literature review supports the rarity of hemorrhage from intraventricular meningiomas.
Implications:
- Recognizing intraventricular meningioma as a cause of stroke-like hemorrhage is crucial.
- Early surgical management of lateral ventricular meningiomas is advised, regardless of size or symptoms.
