摘　　要：Multiple saccular or giant aneurysms of azygos anteriorcerebral artery(AACA) at the distal segments A2-A5 are very rarely reported. Distal anterior cerebral artery(DACA) aneurysms represent approximately 2%-7% of all cerebral aneurysms. We present the case of an Albanian 62-year-old male, admitted at our service after sudden onset of severe headache and vomiting. Computerized tomography(CT) of the head showed hemorrhage in the front of corpus callosum. CT angiography followed by digitally subtracted angiography(DSA) documented a large necked aneurysm with three lobes at the origin of calloso-marginal artery and a single DACA, also known as AACA. A frontal parasagittal craniotomy was performed. Obliteration of the aneurysm was done only by separate clipping of each three lobes at the respective neck. Postoperative DSA demonstrated complete exclusion of the aneurysm and a regular flow of AACA. The patient recovered uneventfully. Despite it is a rare occurrence, an aneurysm of distal segments of anterior cerebral artery A2-A5, concomitant to AACA should be studied with DSA. In the era of embolization, conserving good microsurgical skills is fundamental for dealing with multilobar cerebral aneurysms, associated with rare anatomical variations.Multiple saccular or giant aneurysms of azygos anteriorcerebral artery(AACA) at the distal segments A2-A5 are very rarely reported.
