Abstract:
Objective To study the clinical and MRI features of central pontine myelinolysis after liver transplantation.Methods 3 cases of orthotopic liver transplantation patients,displaying unconsciousness,drowsiness,reduced muscle strength of both lower extremities 3 to 21 days after the operation respectively,went through MRI scan in 2 days.Results MRI showed that symmetric long T1 and T2 signals,high-signal-intensity DWI and low-signal-intensity ADC were found in central pontine region.The cerebral cortex was involved in 2 cases,and abscess in basal ganglia appeared in 1 case.MRI examination showed that 2 cases had decreased lesion range,clear boundary and equal-signal-intensity DWI 35 days and 2 months respectively after.Conclusion MRI is valuable for the diagnosis of the patient with central pontine myelinolysis after liver transplantation.
