脑梗塞是神经科常见病,临床症状典型者诊断不难,但以视力障碍为首发症状的脑梗塞易被误诊。现将脑梗塞误诊为球后视神经炎2例报告如下: 例1:男,56岁。以视力减退20天,加重2天于1988年3月10日就诊于眼科。视力:左眼0.4,右眼0.3。眼节前无异常。视觉诱发电位(VEP)示:各导P_(100)潜伏期明显延长,波幅降低。诊断为“球后视神经炎”。投予地塞米松及维生素B_1口服,治疗一周,症状加重且后枕部痛。3月18日行头部CT扫描:右侧枕叶及左侧枕顶区皮质大片状低密度灶,境界模糊。右侧为2.5×3.Ocm Cerebral infarction is a common neurological disease, clinical symptoms are not difficult to diagnose, but the visual impairment as the first symptom of cerebral infarction easily misdiagnosed. Misdiagnosis of cerebral infarction now as retrobulbar optic neuritis in 2 cases reported as follows: Example 1: Male, 56 years old. To 20 days of vision loss, aggravating 2 days in March 10, 1988 treatment in ophthalmology. Eyesight: left eye 0.4, right eye 0.3. No abnormal eye before the festival. Visual evoked potentials (VEP) showed: each guide P_ (100) significantly prolonged latency, amplitude decreased. Diagnosed as “posterior optic neuritis.” Oral administration of dexamethasone and vitamin B_1, for one week, the symptoms worsened and occipital pain. March 18 Head CT scan: the right occipital lobe and left cortical large cortical low-density lesions, blurred state. The right side is 2.5 × 3.Ocm
