Résumé
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.

Résumé
A 65-year-old female visited us due to gait disturbance. A neurological examination showed cognitive impairment, dystonia, myoclonus, bradykinesia, postural instability, and freezing of gait (FOG). She was diagnosed with extrapontine myelinolysis based on her history of hyponatremia and high signal intensities (HSIs) in both striata on T2-weighted images. Her neurological problems including FOG improved over 25 days. In a follow-up MRI 50 days after the onset, HSIs disappeared in the striata but new ones appeared in the pons. FOG may have been related to striatal dysfunction in this patient.
