T1-weighted MRI of patient 1 (a and b) after generalized status epilepticus and patient 2 (c and d) with a history of cerebellar astrocytoma treated by surgical resection and large field radiation therapy including the occipital lobes and both thalami showing laminar necrosis of both thalami (a and c, arrows) associated with laminar necrosis in the right-sided parietal cortex (b, arrows) and in the bilateral occipital cortex (c, arrowheads). Panel (d) shows the cerebellar cavity due to cerebellar astrocytoma resection.
