Blood supply to the human thalami is complex and multiple variants exist. The artery of Percheron is one of those variants and is characterized by a solitary arterial trunk that branches from one of the proximal segments of either posterior cerebral artery and sup- plies blood to the paramedian thalami. Its occlusion results in bilateral paramedian thalamic infarction sometimes extending to the midbrain. We report a case of bithalamic infarction secondary to occlusion of the artery of Percheron. We will illustrate the complex clinical symptomatology and underscore the role of imaging, especially MRI, for diagnosis.
人类丘脑的血液供应复杂，存在多种变异情况。佩谢隆动脉就是其中一种变异，其特征是有一个单独的动脉干，从大脑后动脉近端的某一段分支出来，为双侧丘脑旁正中区域供血。它的闭塞会导致双侧丘脑旁正中梗死，有时还会延伸至中脑。我们报告一例因佩谢隆动脉闭塞继发的双侧丘脑梗死病例。我们将阐述其复杂的临床症状，并强调影像学检查，尤其是磁共振成像（MRI）在诊断中的作用。
