Sporadic Lateral Ventricular Hemangioblastoma presenting with Intraventricular and Subarachnoid Haemorrhage

Intraventricular hemangioblastoma (hb) is very rare; few cases of intraventricular hb have beenreported in the literature, either sporadically or in association with von hippel-lindau disease. furthermore, the incidence of ventricular haemorrhage from hb seems to be uncommon. we report a unique case of sporadic hb of the right lateral ventricle presenting with intratumoural and intraventricular haemorrhage in addition to multifocal intracranial superficial siderosis, indicating the presence of a subarachnoid haemorrhage (sah) as well. such a combination has not been reported before. in the future, the detection of an intraventricular mass in association with ventricular haemorrhage, with or without sah, should include hb as a differential diagnosis, particularly when the imaging appearances are not typical of the more common intraventricular tumours.
