✦ Synopsis
Magnetic resonance spectroscopy (MRS) and perfusion of central pontine myelinolysis (CPM) have been rarely reported. One case of CPM that developed after liver transplantation was analyzed with serial diffusion-weighted imaging (DWI), MRS and MR perfusion. During the acute phase, a pontine lesion showed an obvious high-signal intensity on DWI with decreased apparent diffusion coefficient value, decreased N-acetylaspartate (NAA)/creatine (Cr) ratio, increased choline (Cho)/Cr ratio and increased perfusion on the cerebral blood volume map. In a later phase, the lesion showed isosignal intensity on DWI, further decreased NAA/Cr ratio, increased Cho/Cr ratio and decreased perfusion. The increase in lesion perfusion during the acute phase may reflect a higher metabolic activity due to an increase in cell number and activity.
