Female, 45 years old, with seizure disorder, occipital seizures, follow-up abnormal MRI from 11/2011. Diffusion restriction and T2 hyperintensity seen on the prior examination within the splenium of the corpus callosum have resolved.No new restricted diffusion is seen. There remain scattered T2 hyperintense lesions in the white matter which are stable in size and number relative to the prior examination.No evidence of parenchymal edema or mass effect is seen. No abnormal extra axial fluid collections are detected. The ventricles are stable and normal in size and morphology.Sequences tailored to the temporal lobes were performed and these show no areas of signal asymmetry or morphologic abnormality. No specific abnormalities are demonstrated in the occipital lobes.
1. Restricted diffusion and T2 hyperintensity seen on the prior examination within the splenium of corpus callosum have resolved without sequelae. These findings may therefore have represented a transient phenomenon related to seizure activity or perhaps medication.2. Scattered T2 hyperintense lesions are demonstrated within the cerebral white matter without significant interval change in size or number. These remain nonspecific and may reflect the sequela of an ischemic, inflammatory or demyelinating process among others.3. No specific abnormalities are detected within the temporal or occipital lobes.
