Susac syndrome is a rare neurologic disorder first described by Susac et al. in 1979. Clinically, Susac syndrome consists of a triad including encephalopathy, branch retinal artery occlusions and sensorineural hearing loss. All three components of the triad usually do not present at the same time, thus delaying time to diagnosis. MRI studies often show characteristic punched out lesions of the central fibers of the corpus callosum. Intracranial leptomeningeal enhancement may be seen, however, cauda equina involvement has not been described to our knowledge. We present a case of Susac syndrome in a middle-aged male with symptoms of cauda equina syndrome, and spinal MRI showing diffuse enhancement of the nerve roots of the cauda equina.
苏萨克综合征是一种罕见的神经系统疾病，1979年由苏萨克等人首次描述。临床上，苏萨克综合征由三联征组成，包括脑病、视网膜分支动脉阻塞和感音神经性听力损失。三联征的所有三个组成部分通常不会同时出现，因此会延迟诊断时间。MRI研究常显示胼胝体中央纤维有特征性的打孔样病变。可能会出现颅内软脑膜强化，然而，据我们所知，马尾受累情况尚未见报道。我们报告一例中年男性苏萨克综合征病例，该患者有马尾综合征症状，脊髓MRI显示马尾神经根弥漫性强化。
