The paramedian artery arises from P1 segment of posterior cerebral artery and supplies a variable extent of thalamus but usually the dorsomedian, median, internal medullary lamina and the intralaminar nuclei. The typical clinical picture of unilateral paramedian thalamic infarctions consist of arousal and memory disorders, language or visuospatial disorders depending on the side of the lesion accompanied with gaze palsies and sensory-motor deficits. Ipsilateral ptosis associated with paramedian thalamic infarctions has been rarely reported. We report a 31 years old patient presenting with unilateral ptosis and right sided facial numbness associated with right paramedian thalamic infarction.
旁正中动脉起源于大脑后动脉P1段,供应不同范围的丘脑,但通常供应背内侧、内侧、内髓板和板内核。单侧旁正中丘脑梗死的典型临床表现包括觉醒和记忆障碍、根据病变部位不同出现语言或视觉空间障碍,伴有凝视麻痹和感觉运动功能缺损。与旁正中丘脑梗死相关的同侧上睑下垂鲜有报道。我们报告1例31岁患者,出现单侧上睑下垂和右侧面部麻木,与右侧旁正中丘脑梗死有关。
