Abstract:
Objective To analyze the imaging features of acute and subacute toxic encephalopathy induced by organic solvents.Methods A total of 8 cases with acute and subacute toxic encephalopathy induced by organic solvents were retrospectively enrolled,and all imaging data were further analyzed.Of 8 patients,all patients underwent the plain CT scan,there were 3 patients with plain and enhanced cranial MR scan,and 2 patients with plain cranial MR scan.Results White matter density on CT imaging was signifi-cantly and symmetrically decreased in all cases,but the involvement of gray matter nuclei was unclear.White matter involvement on MRI was diffuse and symmetrical on both hemispheres.There were differences in white matter among affected areas.The gray mat-ter nuclei in the cerebellar dentate nucleus,globus pallidus,and thalamus were most involved,but there was no evidence of involve-ment in the white matter of the lateral ventricle,corpus callosum,and temporal pole.All lesions were with high signal on the diffu-sion weighted imaging(DWI)and high and low signals on apparent diffusion coefficient(ADC)map and without enhancement.Con-clusion The lateral ventricle white matter,corpus callosum,and temporal pole white matter are not easily affected in cerebral white matter in patients with organic solvents toxic encephalopathy,contributing to differentiate from other toxic encephalopathies.
