摘要："BACKGROUNDInfarction of the conus medullaris is a rare form of spinal cord infarction. The first symptom is usually acute non-characteristic lumbar pain, followed by lower limb pain, saddle numbness, fecal incontinence, and sexual dysfunction. Spontaneous conus infarction with ""snake-eye appearance"" on magnetic resonance imaging has rarely been reported.CASE SUMMARYWe report a 79-year-old male patient with spontaneous conus infarction who had acute lower extremity pain and dysuria as the first symptoms. He did not have any recent history of aortic surgery and trauma. Magnetic resonance imaging revealed a rare ""snake-eye appearance."" In addition, we reviewed the literature on 23 similar cases and summarized the clinical features and magnetic resonance manifestations of common diseases related to the ""snake-eye sign"" to explore the etiology, imaging findings, and prognosis of spontaneous conus infarction.CONCLUSIONWe conclude that acute onset of conus medullaris syndrome combined with ""snake-eye appearance"" should be strongly suspected as conus medullaris infarction caused by anterior spinal artery ischemia. This special imaging manifestation is helpful in the early diagnosis and treatment of conus infarction."
