UNASSIGNED: A 47-year-old female who presented with bilateral tinnitus and vision changes was found to have bilateral sensorineural hearing loss and many bilateral retinal arteriolar Gass plaques. She had bilateral scotomas corresponding with temporal thinning and atrophy of the inner nuclear layer (INL) on OCT. Retinal examination and fluorescein angiography demonstrated minimal arteriolar wall hyperfluorescence with no evidence of acute branch retinal artery occlusion. She developed daily headaches. MRI of the brain was normal with no corpus callosal lesions. She was diagnosed with probable Susac syndrome based on the above findings.
UNASSIGNED: Our patient\'s bilateral high frequency sensorineural hearing loss, numerous bilateral Gass plaques, and headaches are most likely attributable to Susac syndrome. While BRAO is considered a cornerstone of retinal involvement in Susac syndrome, it may only be appreciable angiographically in the acute setting, and it is important to recognize Gass plaques as a significant diagnostic marker of disease.
■一名47岁女性出现双侧耳鸣和视力变化,被发现有双侧感音神经性听力损失和许多双侧视网膜小动脉血管斑块。在OCT上,她的双侧暗点与颞叶变薄和内核层(INL)萎缩相对应。视网膜检查和荧光素血管造影显示小动脉壁高度荧光,没有急性视网膜分支动脉阻塞的证据。她每天都出现头痛。头颅MRI正常,无call体病变。根据上述发现,她被诊断为可能的Susac综合征。
■我们患者的双侧高频感音神经性听力损失,许多双侧Gass斑块,头痛很可能是Susac综合征引起的.虽然BRAO被认为是Susac综合征视网膜受累的基石,它可能只有在急性背景下的血管造影才能感知,重要的是认识到Gass斑块是疾病的重要诊断标记。
