A rare case of an isolated intraventricular tuberculoma with a dismal outcome: an unusual location of a common pathology and lessons learnt.

Isolated involvement of the ventricle by tuberculosis is extremely rare and only nine cases have been reported till now. We report a 13-year-old immuno-competent boy who presented with features of raised intracranial pressure with altered sensorium. Computed Tomography showed a ring enhancing intraventricular lesion with obstructive hydrocephalus. Gross total resection of the lesion was achieved and diagnosis was confirmed histologically. The patient had medical complications in the postoperative period and succumbs five days after the surgery. This report presents the unusual location of a common disease with a review of its clinical, radiological and histopathological features as well as the treatment modalities available.
