Susac syndrome is a rare disease presenting with a classic triad of symptoms. These are sensorineural hearing loss, encephalopathy, and branch retinal artery occlusions. Initial presentation is usually headache and symptoms of encephalopathy. Hearing loss is unusual in the early stages but, when it does present, can often lead to a misdiagnosis of sudden sensorineural hearing loss. Hence, neurological and retinal examinations are essential to an accurate diagnosis. In this study, we aimed to raise awareness of Susac syndrome among physicians and facilitate recognition of its manifestation, especially in those patients presenting with hearing loss alone. Identifying Susac syndrome that presents as sudden sensorineural hearing loss can be challenging but a number of case reviews have been reported in recent years and treatment guidelines are available.

Susac 综合征是一种罕见的疾病，具有典型的三联征症状。这些是感音神经性听力损失、脑病和视网膜分支动脉闭塞。最初的表现通常是头痛和脑病的症状。听力损失在早期并不常见，但一旦出现，往往会导致误诊为突发感音神经性听力损失。因此，神经系统和视网膜检查对于准确诊断至关重要。在这项研究中，我们旨在提高医生对 Susac 综合征的认识并促进对其表现的认识，特别是在那些仅表现为听力损失的患者中。
