Congenital agenesis of the internal carotid artery is a rare malformation. Although the condition can be regarded as a normal variant, recognition and knowledge of such an entity is important because it has important implications during carotid and trans-sphenoidal surgery and interventional stenting. Congenital agenesis of the internal carotid artery is also associated with other vascular abnormalities such as cerebral aneurysms. This report is of a patient with congenital agenesis of the right internal carotid artery that was detected incidentally by computed tomography scan.

頸內動脈先天性發育不全屬於罕見的畸形病例。雖然這種情況可介定為正常變異，但由於這種病在 進行頸動脈和經蝶竇手術以及介入支架植入術時具重要的意義，所以對此病症的認識和理解不可或 缺。頸內動脈先天性發育不全亦會與其他血管畸形如顱內動脈瘤相關。本文報告一宗進行電腦斷層 造影檢查時偶然發現的右頸內動脈先天性發育不全的病例。
