Cavernoma of the lateral ventricule presenting as speech arrests

Abstract

Cavernous malformations (CM) are formed by dilated thin-walled vascular channels without intervening parenchyma and intraventricular lesions are rare. We report a case of an intraventricular cavernoma in a 54-year old female patient. She presented with speech arrests daily for 10 months. Neurological examination revealed no deficits. The brain MRI study revealed an intraventricular lesion at the level of the left atrium, heterogeneously hyperintense on both T1 and T2-weighted images. It was performed an interhemispheric transcallosal approach with gross-total resection of the lesion. The histological examination was compatible with the diagnosis of cavernous haemangioma. In the postoperative period the patient presented with transient right hemiparesis with recovery in two weeks. We briefly review the literature concerning intraventricular cavernomas.
