Fig 2. Patient 4 (6 years old) with IAEE and fever and sudden-onset convulsion on day 3. A, Single ovoid well-defined splenial lesion (arrowheads) is slightly hyperintense on the T2-weighted axial image. B, The lesion (arrowheads) has prominently high signal intensity on isotropic DWI. C, ADC value of 0.34 ± 10–3 mm2/s obtained from the region of interest located in the lesion reveals restricted diffusion on ADC map image. D, Follow-up study on day 9 shows complete resolution of diffusion restriction on isotropic DWI.
