Core Tip

Core Tip: Infarction of the conus medullaris is a rare form of spinal cord infarction, and there is no specific examination method in clinic. On the other hand, the "Snake-Eye Appearance" on the diffusion-weighted imaging sequence of magnetic resonance imaging highly suggests spinal cord infarction, although few cases of conus infarction have been reported. This special imaging manifestation is helpful in the early diagnosis and treatment of conus infarction.
