A5 segment aneurysm of the anterior cerebral artery, imbedded into the body of the corpus callosum: A case report
نویسندگان
چکیده
BACKGROUND The A5 segment aneurysms of the anterior cerebral artery are rare, approximately 0.5% of all intracranial aneurysms. They are small with a wide base located in the midline, with the domes mostly projecting upward or backward. CASE DESCRIPTION The authors describe a unique case of A5 segment aneurysm, with the dome embedded into the body of the corpus callosum. This 41-year-old female was admitted to the neurology department for possible multiple sclerosis investigation. Computed tomography angiogram (CTA) revealed a 4-mm right-sided pericallosal artery aneurysm, with rare configuration, which was caudally projected, embedded into the body of the corpus callosum. Considering the family history, patient underwent a prophylactic ligation surgery. The postoperative CT and CTA showed no complication and successful occlusion of the aneurysm with no ischemia or hemorrhage in the corpus callosum. CONCLUSION To the best of our knowledge, this is the first case of an aneurysm with this configuration. Our rare case of A5 segment aneurysm demonstrates the importance of planning of the surgery, choosing the appropriate approach, and knowing the detailed anatomy of the region, as well as the necessity of microsurgical clipping of small unruptured AdistAs.

Fenestrated azygos A2 segment: a rare anatomic variation
Advancement in neurovascular imaging has led to detection of abnormalities and normal anatomic variations. Most of anatomical variations in cerebral vasculature are asymptomatic and found incidentally; however, some may increase the risk of aneurysm formation and subsequent subarachnoid or intracranial hemorrhage. Here in, we report fenestration within an azygos A2 segment, as an incidental fin...

The aim of the present study was to quantify the distribution of the elastic fiber system within the wall of the anterior cerebral artery. The study is based on the works of Glynn (1940) and Stehbens (1989) concerning the incidence and origin of brain aneurysms and recent studies of the elastic fibers. The anterior cerebral artery was divided into three segments, S1, S2 and S3: S1 corresponds t...

Background: X-linked lissencephaly with ambiguous genitalia (XLAG) is a recently described genetic disorder, in which patients present with lissencephaly, agenesis of the corpus callosum, refractory epilepsy of neonatal onset, acquired microcephaly, and male genotype with ambiguous genitalia. XLAG is responsible for a severe neurological disorder of neonatal onset in boys. A gyration defect con...
متن کاملCase report : the clinical significance of an azygous anterior cerebral artery
The circle of Willis was originally described in 1664 [1]. The circle of Willis is a structure receiving arterial blood supply from the internal carotid and basilar arteries. The circle allows for the equalization of blood flow between cerebral hemispheres allowing for anastomotic circulation [2, 3]. The circle of Willis then divides into 3 paired vascular divisions: anterior, middle and poster...
