 MRI brain:There has been interval resolution of previously seen multiple areas of bilateral T2/FLAIR hyperintensity predominantly involving the cortex and subcortical white matter. There are no areas of abnormal signal or pathologic enhancement. The ventricles and sulci are prominent, consistent with mild global volume loss greater than expected for the patient's stated age. The cisterns remain patent. There is no midline shift or mass effect. There is no diffusion abnormality. No extra-axial fluid collection is identified.Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits. There is mild mucosal thickening of the frontal sinuses, ethmoid air cells and bilateral maxillary sinuses. MRA brain:The intracranial internal carotid arteries are normal in course and caliber. Slightly inhomogeneous areas of flow related enhancement in the cavernous carotids likely relates to turbulence and flow related artifact. The middle and anterior cerebral arteries are unremarkable. The vertebral arteries, basilar artery and posterior cerebral arteries are normal in course and caliber. There is no evidence of flow-limiting stenosis or aneurysm.
1. Interval complete resolution of previously seen scattered prominent areas of abnormal cortical and subcortical abnormal signal, presumably related to PRES as well as possible superimposed areas of seizure activity given history of status epilepticus.2. No evidence of acute infarct.3. Unremarkable MRA of the head.
