Magnetic resonance imaging, single-photon emission computed tomography, and magnetoencephalography at the age of 4 months. (a) Brain magnetic resonance imaging scan showing a slightly hyperintense lesion on T1-weighted images and cortical atrophy in the right frontal lobe involving the superior and medial frontal gyri and in the left parietal lobe. (b) Axial and coronal sections of ictal single-photon emission computed tomography scans. Increased perfusion was seen over the right central region (white encircled area). (c) A three-dimensional image and sagittal sections of the interictal magnetoencephalography scans. The region encircled by the white line indicates the cortical tuber. Spike dipoles were clustered at the pericortical tuber, and only one spike dipole was detected above the cortical tuber.
