To report the clinical course and magnetic resonance imaging (MRI) findings in a 28-year-old woman with preeclampsia and reversible cortical blindness.
Interventional case report.
The patient presented at the 37th week of pregnancy with headache and hypertension. The next day, her visual acuity decreased to light perception in both eyes. After emergent cesarean section, examination revealed reactive pupils and normal fundi.
Magnetic resonance imaging of the brain showed areas of increased signal in both occipital lobes. One month later, at which time the patient's visual acuity had returned to 20/20, follow-up MRI showed complete resolution of radiologic abnormalities.
Cortical blindness is a rare complication of preeclampsia. In this case, cortical blindness was reversible and most likely due to vasogenic edema rather than vasospasm.
报告一名患有先兆子痫和可逆性皮质盲的28岁女性的临床病程及磁共振成像（MRI）表现。
介入性病例报告。
该患者在妊娠第37周时出现头痛和高血压。次日，其双眼视力降至光感。紧急剖宫产术后检查发现瞳孔反应正常且眼底正常。
脑部磁共振成像显示双侧枕叶信号增强区域。一个月后，此时患者视力已恢复至20/20，随访MRI显示影像学异常完全消退。
皮质盲是先兆子痫的一种罕见并发症。在此病例中，皮质盲是可逆的，极有可能是由血管源性水肿而非血管痉挛所致。
