Two cases of cerebral venous angiomas associated with saccular aneurysms are reported. The incidence of such cases is very rare and only two cases have so far been reported in the literature. The first case was a 65-year-old female, who was admitted because of convulsive seizures. Neurological examination revealed right-sided cerebellar signs. Post-contrast computed tomography (CT) scan showed an irregularly shaped high-density area in the right cerebellar hemisphere. Cerebral angiography revealed a characteristic venous angioma in the right cerebellar hemisphere, and a saccular aneurysm of the right internal carotid artery. This patient was treated conservatively. The second case was a 44-year-old female, who was admitted because of severe headache and vomiting. Neurological examination revealed neck stiffness and right oculomotor palsy. CT scan showed a linearly enhanced lesion in the right frontal paraventricular region. Carotid angiography revealed a venous angioma in the right frontal lobe, and a right internal carotid-posterior communicating aneurysm. The aneurysm was clipped, but the venous angioma was treated conservatively. A review of the literature suggests the possibility of coincidental association of cerebral aneurysm with cerebral venous angioma as congenital vascular anomalies. The incidence of venous angioma associated with aneurysm should be higher than previously reported, if the angiogram of subarachnoid hemorrhage is carefully reviewed with serial venograms.
