Case #15


Findings

  • T2/FLAIR signal hyperintensity and restricted diffusion in the central pons with peripheral sparing and no associated mass effect
  • No associated enhancement
  • No evidence of acute hemorrhage or hydrocephalus


Diagnosis

  • Osmotic demyelination

Sample Report

T2/FLAIR signal hyperintensity and restricted diffusion in the central pons without associated mass effect or enhancement, which is primarily concerning for osmotic demyelination (central pontine myelinolysis). Recommend correlation with serum sodium measurements.
