ABSTRACT

Bilateral infarction in the anterior cerebral artery vascular territory is very rarely seen and usually results from rupture of an aneurysm of the anterior communicating artery or from thrombosis of the precommunicating part of the anterior cerebral artery in combination with an agenesis of the contralateral part. Our first case, a 40 year old right-handed man, presented with headache and tomography of the brain showed a subarachnoid hemorrhage. In the follow-up process, magnetic resonance imaging of the brain was made upon development of paraparesis, ischemic infarct was detected in the bilateral anterior cerebral artery territory and it was considered that the reason of infarction could be vasospasm. In his digital subtraction angiography, multiple aneurysms were detected. Our second case, a 57 year old right-handed man, presented with a sudden loss of consciousness, tomography of the brain showed subarachnoid hemorrhage. Embolization was applied upon detecting an aneurysm of the anterior communicating artery in his digital subtraction angiography,and confusion, total aphasia, tetraparesis and urinary incontinence occurred after embolization. Magnetic resonance imaging of the brain showed acute ischemic infarction in the bilateral anterior and median cerebral artery territory. Embolism and vasospasm were thought to be the reason for the infarction. Because of being rare, our cases were presented together with the relevant literature.
