title: [Ruptured fusiform aneurysm of the supreme anterior communicating artery: a case report].
abstract: The supreme anterior communicating artery (SAcom) is a very rare anomaly that appears as a communicating artery between the anterior cerebral arteries (ACAs). This anomaly was first reported by Laitinen and Snellman in 1960. They described the SAcom as a connection between both pericallosal bifurcations. They also suggest that the SAcom may be an embryological remnant and a cause of aneurysm formation. A distal ACA aneurysm can be associated with the SAcom. In this case report, we describe a ruptured fusiform aneurysm originating from the SAcom. We treated the patient by trapping the SAcom along with the aneurysm. This is the first case report regarding a ruptured fusiform aneurysm originating from the SAcom itself.
