本组７１例脑干梗塞患者均作ＭＲＩ检查，其中５４例为亚临床病变，其临床表现与ＭＲＩ所见的病灶不符，且５４例均在ＭＲＩ检查前误诊，误诊率为７９％（５４／７１），误诊病种达１２种，且尤以误诊为颈内动脉系统梗塞最多（３２例），同时发现一些单颅神经损害和所谓的＂椎动脉供血不足＂实为脑于梗塞所致。最后本文对上述情况进行讨论。 The group of 71 patients with brain stem infarction were MRI examination, of which 54 were subclinical lesions, the clinical manifestations and MRI lesions seen in 54 patients were misdiagnosed before MRI examination, the misdiagnosis rate was 79% (54 / 71), misdiagnosis of 12 species, and especially misdiagnosed as the most internal carotid artery infarction (32 cases), and found that some cranial nerve damage and the so-called “vertebral artery insufficiency” is actually caused by the brain in the infarct. Finally, this article discusses the above situation.
