EEG and cranial MRI. (A). EEG of the patient at age 7 months. Abnormal background rhythm was found. (B-C). Axial T1MI and T2MI on Cranial MRI. Symmetric patchy abnormal signals in the bilateral parietal white matter and adjacent to the bilateral lateral ventricles, and insufficient cerebral white matter myelination were observed. The nuclei in the bilateral basal ganglia showed symmetric slightly short T1 and slightly short T2 signals; the bilateral lateral paraventricular region and bilateral parietal white matter revealed symmetric patchy slightly long T1 and slightly long T2 signals, isointense signals on fluid attenuated inversion recovery (FLAIR) image, and slightly low-intense signal with indistinct edges on diffusion weighted imaging (DWI).
