Cortical Laminar Necrosis associated with Osmotic Demyelination Syndrome.
Cortical laminar necrosis has been rarely observed in osmotic demyelination syndrome. We report a 32-year-old female patient who became comatose after the rapid correction of hyponatremia. There were high signal intensities in the pons and bilateral deep gray nuclei on T2-weighted MRI images, and linear hyperintensities along the cerebral cortices on T1-weighted images with a diffuse gyriform enhancement. MR spectroscopic findings showed a decrease of the N-acetyl aspartate peak and an increase in those of the lipid and lactate complex. The case demonstrates that a severe form of osmotic demyelination syndrome accompanying cortical laminar necrosis can result from the rapid correction of hyponatremia.
