title: Intraventricular cavernous hemangioma at the foramen of Monro: Case report and literature review.
abstract: Cavernous hemangiomas rarely occur in the cerebral ventricles. Those occurring at the foramen of Monro are even less frequent. So far, only eight cases of cavernous hemangioma at the foramen of Monro have been reported in the literature. Here, we present a similar case and correlated the radiographic with the histopathologic findings of the patient. A 51-year-old woman was admitted with obstructive hydrocephalus-related symptoms. The computed tomography (CT) and magnetic resonance imaging (MRI) revealed a partly calcified lesion with slight contrast enhancement located in the area of the right foramen of Monro. The lesion was completely removed by surgical resection with a transfrontal transventricular approach. The resected mass was histologically diagnosed as cavernous hemangioma. The patient's symptoms resolved immediately after operation. Cavernous hemangioma at the foramen of Monro in the present case had common MRI features as previously reported. Although MRI can provide initial diagnosis for such unusually localized tumor, it should be confirmed histopathologically.
