Abstract

A 77-year-old female with a history of osteoarthritis visited our clinic complaining of lower back pain, paresthesia in both legs, and voiding difficulty. Her pain and temperature sensations were diminished below the L1 dermatome, and proprioception was decreased in both feet. The findings of a routine laboratory workup, echocardiogram, and cerebrospinal fluid studies were normal. Spine magnetic resonance imaging revealed high T2-weighted signal intensities and diffusion restriction in the posterior conus medullaris. The patient was diagnosed and treated for posterior spinal artery infarction.
