Conventional MRI of the brain demonstrates diffuse abnormal signal and vasogenic edema involving the left temporal lobe and abnormally dilated supratentorial ventricular system.
High T1 signal of the left occipital lobe cortex representing areas of cortical laminar necrosis as well as the high signal of the left occipital horn well demonstrated on axial T1 and axial FLAIR (ventricular debris). Associated transependymal oedema.
DWI and ADC show area of restricted diffusion within the left temporal lobe and the left occipital horn content.
Post-contrast images demonstrate a left temporal lesion with ring enhancement pattern as well as ependymal enhancement of the left lateral ventricular wall.
