title: Lateral ventricular meningioma presenting with intraventricular hemorrhage: a case report and literature review.
abstract: Lateral ventricular meningiomas presenting with primary intraventricular hemorrhage are extremely uncommon. We report here a case of primary intraventricular hemorrhage attributable to a lateral ventricular meningioma. This case concerns a 46-year-old female patient who presented with sudden onset of headache. Computed tomography (CT), computed tomography angiography (CTA) and magnetic resonance imaging (MRI) examinations showed hemorrhage from a ruptured tumor mass, which was pathologically confirmed as a transitional meningioma. The patient underwent surgical treatment and had a good prognosis. A retrospective review of eight previous cases of hemorrhage from ruptured lateral ventricular meningiomas revealed that hemorrhage of lateral ventricular meningiomas and hemorrhage of meningiomas at other intracranial sites have similar causes. The clinical and pathological features of ruptured lateral ventricular meningiomas are consistent with those of unruptured lateral ventricular meningiomas. As this clinical entity is extremely rare, attention is called for while performing differential diagnosis.
