A 32-year old man presented with a bilateral faciobrachial paresis, pyramidal signs in the upper limbs and dysarthria. Computer tomographic (CT-)scans showed bilateral cortical zones of contrast enhancement and strikingly symmetrical capsular hypodensities. Angiography revealed a stenosis of the left internal carotid artery and an occlusion of the right internal carotid artery. Essential thrombocythemia was diagnosed as the underlying disorder. Since there are no indications of pontine lesions, we assume that the signs and symptoms in this patient could mainly be attributed to the bilateral capsular lesions, that resemble lacunar infarcts.
一名32岁男性出现双侧面臂轻瘫、上肢锥体束征及构音障碍。计算机断层扫描（CT）显示双侧皮质强化区及明显对称的囊腔低密度影。血管造影显示左颈内动脉狭窄及右颈内动脉闭塞。诊断潜在疾病为原发性血小板增多症。由于没有脑桥病变的迹象，我们认为该患者的体征和症状主要归因于双侧囊腔病变，类似于腔隙性梗死。
