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.

Intraventricular cerebral aneurysms are rare neurovascular diseases
Our objective is to review the unusual location of this aneurysm, its relationship to an arteriovenous malformation (AVM) and other conditions and the type of treatment used in this case
Cerebral angiography showed the presence of a posterior right temporal AVM Spetzler-Martin grade (SM) II, 40 × 15 × 10 mm, with two main feeders: a deep afferent is the lateral posterior choroidal artery, in which way a distal aneurysm 2 × 7 mm was observed (Figure 1 and Figure 2) and the other is the anterior temporal artery (Figure 3 and Figure 4); plus small dural feeders of the superficial temporal artery with one superficial drainage vein to the sigmoid sinus
Summary
Intraventricular cerebral aneurysms are rare neurovascular diseases. Only less than 50 cases have been. How to cite this paper: Calle, J.L., et al (2016) Clipping of Lateral Posterior Choroidal Intraventricular Aneurysm Related to Ruptured Temporal Arteriovenous Malformation: Case Report. Open Journal of Modern Neurosurgery, 6, 9-15. Calle et al reported worldwide, so the few aspects known have made the management of such aneurysms difficult, despite its deep location, small size and peculiar angiographic characteristics. Even rarer are the distal flow-related intraventricular aneurysms in the context of an AVM with only two previous cases reported. Our objective is to review the unusual location of this aneurysm, its relationship to an AVM and other conditions and the type of treatment used in this case
