title: Malignant fibrous histiocytoma presenting as an intraventricular mass five years after incidental detection of a mass lesion.
abstract: Malignant fibrous histiocytoma is a rare intracranial neoplasm. It usually presents as a meningeal mass but occurs also intraaxially. Few information is available on cellular origin, premalignant histologic stages and time course of malignant transformation. We report a case of a primary intraventricular malignant fibrous histiocytoma in a patient who five years prior to clinical manifestation of the malignancy was found to have an intraventricular mass with benign CT characteristics.
