In three cases of cerebral malaria,MR imaging disclosed either cortical infarcts(one case)or hyperintense areas of white matter(two cases)on T2- weighted and fluid-attenuated inversion-recovery sequences.These white matter abnormalities were,in one case,sharply limited,symmetrical, hyperintense,and unenhanced;in the other case,they were diffuse, hyperintense,and had a more limited focus.The diffuse hyperintensity was probably due to edema,whereas focal lesions were probably associated with gliosis. |
