Agenesis, aplasia and hypoplasia of the internal carotid artery are rare congenital malformations. They are usually asymptomatic and incidentally discovered through ultrasound or imagistic tests. The aim of this study is to improve their management in our Departments. We report here the case of a 39-year-old woman addressed to our ambulatory in 2013 for benign symptoms like dizziness and headache. Imagistic findings (magnetic resonance imaging of the brain, and cervical spine, and magnetic resonance angiography of the head and neck) indicated a very rare condition: left internal carotid artery agenesis accompanied by the absence of the pre-communicant part of the left anterior cerebral artery and of the right posterior communicating artery. Internal carotid artery agenesis is an uncommon congenital anomaly and it could be misdiagnosed as stenosis/occlusion of this artery. This condition is important to be recognized due to the associated hemodynamic changes and in order to discover and evaluate other accompanying vascular malformations (aneurysms, collateral channels) and their life threatening potential risks (subarachnoid hemorrhage or ischemia). Also, it has a special importance in case of planning carotid or trans-sphenoidal hypophyseal surgery.
颈内动脉发育不全、发育不良和发育异常是罕见的先天性畸形。它们通常无症状，通过超声或影像学检查偶然发现。本研究的目的是改善我们科室对它们的管理。我们在此报告一例39岁女性患者，2013年因头晕和头痛等良性症状前来我们的门诊就诊。影像学检查结果（脑部和颈椎的磁共振成像，以及头颈部的磁共振血管造影）显示了一种非常罕见的情况：左侧颈内动脉发育不全，同时左侧大脑前动脉交通前段和右侧后交通动脉缺如。颈内动脉发育不全是一种不常见的先天性异常，可能会被误诊为该动脉的狭窄/闭塞。由于相关的血流动力学变化，以及为了发现和评估其他伴随的血管畸形（动脉瘤、侧支通道）及其危及生命的潜在风险（蛛网膜下腔出血或缺血），识别这种情况很重要。此外，在计划进行颈动脉或经蝶垂体手术时，它也具有特殊的重要性。
