Myeloneuropathy in a dentist.
We present a case of a 49-year-old male dentist with myeloneuropathy. He used nitrous oxide frequently in his practice, and denied recreational use. Magnetic resonance imaging (MRI) of his cervical and thoracic spinal cord demonstrated a hyperintense signal on T2 within the posterior columns. The patient was treated with vitamin B12 and l-methionine. A repeat MRI of his cervical spinal cord 3 months after hospital discharge showed complete regression of the hyperintense signal on T2 within the posterior columns.
