Abstract:
Objective To explore the MRI findings of Wernicke encephalopathy so that to improve the knowledge of this disease.Methods MRI data of Wernicke encephalopathy in 7 cases were retrospectively analyzed.Results Symmetrical abnormal signal intensity was appeared in bilateral thalamus and the area around the third cerebral ventricle in 6 cases,in the area around aqueduct and pontine in 7 cases and in mammillary body,hypothalamus,fornix and the four cerebal ventricles in 2 cases.Above mentioned lesions showed long T1 and long T2 signal intensity and high signal intensity on fluid-attenuated inversion recovery(FLAIR),and high signal intensity on DWI in 2 cases.The lesions were enhanced in 2 cases and small vessels were radial enhancement around lateral ventricle in 1 case after administration of Gd-DTPA.Conclusion Wernicke encephalopathy has definite MR imaging findings,which is of important value in clinical diagnosis and treatment.
