Abstract：
Documented cases of ipsilateral ptosis caused by midbrain infarction remain rare. Herein, we present a patient with isolated ipsilateral ptosis that was initially considered to be a consequence of myasthenia gravis but was subsequently attributed to ventral midbrain infarction. We also discuss the possible underlying mechanisms; ipsilateral ptosis in our patient was attributed to selective damage of the levator palpebral muscle branch of the oculomotor nerve. The patient was started on aspirin (200 mg once daily) and atorvastatin (40 mg once daily). Improvement in ptosis occurred from day 5 of admission, and the patient was subsequently discharged. Ptosis disappeared 1 month after onset. This report describes an extremely rare case of ventral midbrain infarction presenting with isolated ipsilateral ptosis. Careful examination, including magnetic resonance imaging, is essential in such patients, especially in those with multiple cerebrovascular risk factors.
摘要：
记录的由中脑梗塞引起的同侧下垂病例仍然很少见。在这里，我们介绍了一例孤立的同侧上睑下垂患者,最初被认为是重症肌无力的结果,但随后被归因于腹侧中脑梗塞.我们还讨论了可能的潜在机制；我们患者的同侧上睑下垂归因于动眼神经提上睑肌分支的选择性损伤。患者开始服用阿司匹林（200mg，每日一次）和阿托伐他汀（40mg，每日一次）。从入院第5天开始出现上睑下垂改善，患者随后出院。发病1个月后眼睑消失。本报告描述了极为罕见的腹侧中脑梗塞病例，表现为孤立的同侧下垂。仔细检查,包括磁共振成像，对这类病人来说是必不可少的，尤其是那些有多种脑血管危险因素的人。
