Objective To elucidate the imaging characteristics of spongiform leukoencephalopathy induced by heroin and the diagnostic value of MRI *** Eleven cases of heroin addiction were examined by *** sequences included T1-weighted imaging(T1WI),T2-weighted imaging(T2WI)and fast fluid-attenuated inversion recovery pulse sequence(Flair).Results Bilateral symmetrical lesions were located in the white matter of the cerebrum and cerebellum,the internal capsule in all cases,and the callosum in 6 *** lesions in the mesencephalon were found in two *** lesions were shown as hypointense signals on T1WI and hyperintense signals on T2WI and Flair's *** white matter suffered more severely,but the dentate nuclei were not *** Heroin-induced spongiform leukoencephalopathy has characteristic patterns in MRI,which are very specific to this form of the disease.
