Intraventricular glioblastoma multiforme mimicking meningioma and review of the literature

Glioblastoma multiforme (GBM) is the most common primary brain tumor and is usually found in aged persons in the cerebral hemispheres particularly the frontotemporal region. But intraventricular GBM is rare and only few cases have been reported in the literature. We report a case of a 27-year-old man who presented with headache, vision loss in both eyes, and other signs and symptoms of increased intracranial pressure. Computed tomography and magnetic resonance imaging showed an intraventricular, well-circumscribed lesion with homogeneous enhancement of contrast, suggestive of meningioma that is more common than GBM in this location. The patient underwent surgical removal through transcortical route. The final pathologic diagnosis was GBM. We present the clinical features, radiological findings, and surgical management of this case and discuss the pathogenesis and review of the literature of intraventricular GBM.
