MR perfusion of CPM was not reported. One case of CPM after liver transplantation was performed with DWI, MRS, MR perfusion. On acute phase, pontine lesion showed obviously high signal intensity on DWI with a decreased ADC value, decreased NAA / Cr ratio and increased Cho/Cr ratio, increased perfusion on CBV map. On later phase, lesion showed iso-signal intensity on DWI, further decreased NAA / Cr ratio and increased Cho/Cr ratio, decreased perfusion. The increase in lesion perfusion in acute phase may reflect higher metabolic activity due to an increase in cell number and activity.
