ABSTRACT: Background: Intraventricular cerebral aneurysms are uncommon brain vascular disease in general population. The previous reported cases point with more frequency to Moyamoya disease as the main factor to originate aneurysms in the choroidal arteries. Those related to an AVM are even rarer and only two cases have been previously reported. Aim: To discuss the unusual location of this aneurysm, its relationship to other conditions and the type of treatment. Case Presentation: We present the case of a patient with a non-ruptured intraventricular aneurysm of lateral posterior choroidal artery related to a ruptured right temporal arteriovenous malformation, who was successfully treated by clipping immediately, after resection of the malformation. Conclusion: Intraventricular choroidal artery aneurysm is a rare pathology. Its deep location makes the treatment challenging but mandatory due to the high probability of bleeding, especially those flow-related to an arteriovenous malformation.
