Intraventricular meningioma: Neurosurgical challenge worth taking

Intraventricular meningiomas (IVM) are rare and constitutes only 1% of all such tumours, intracranially. This is supported by the fact that there had only been two case series from India. Both these studies are from major centres and have reported just nine and twelve cases of IVM respectively, over a span of twelve years. As compared to larger lesions, smaller ones do not manifest early, due to sufficient accommodating space provided by the ventricular system. Large lesions often present with features of raised intracranial pressure, with or without localising signs, and sometimes with visual field cuts. We encountered one such large intraventricular lesion, in the trigone of left lateral ventricle of a thirty-five-year-old female, who had a hydrocephalic attack & operated upon early. Lesion was confirmed to be a fibroblastic meningioma. Appropriate & timely surgical intervention has potential to save life of these patient. Possibility of such encapsulated lesion should always be kept in mind with clinico-radiological coherence.
