This report describes a rare case of infundibular dilatation perforating the branch of an anterior communication artery (AcomA) which mimicked an AcomA aneurysm. Case Description: The 54-year-old female presented with acute headache in the left temporal area with the right hemianesthesia. The magnetic resonance imaging and magnetic resonance angiography of the brain revealed a small outpouching lesion arising from the medial wall of the proximal A2 of the left ACA presenting as a suspected AcomA aneurysm. The cerebral angiogram showed a funnel-shaped dilatation of the anterior communicating artery with a single perforating branch arising from a dome size 1.4 × 1.1 mm, compatible with an infundibular dilatation perforating a branch of the AcomA. Conclusion: The infundibular dilatation perforating vessel of AcomA is a rare condition and can mimic an AcomA aneurysm. Three-dimensional angiography helps to evaluate differentiation of the characteristics enabling accurate diagnosis.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/e63ed65f-6e2f-49b1-a795-ea0663068d57/featured/hero-1781560753742.png","publishDate":"2022-11-11T00:00:00.000Z","doi":"10.25259/SNI_905_2022","categories":["Neurovascular","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2022/11/11991/SNI-13-525.pdf"}
