History of TBI (subarachnoid bleed) presented with simple partial seizure, found to have left occipital dislocation seen on EEG. There are a few scattered foci of subarachnoid susceptibility effect in the bilateral parietal regions, left more than right. There is volume loss in the right frontal lobe periventricular white matter with trace T2 hyperintensity associated ex vacuo dilatation of the frontal horn of the right lateral ventricle. There is no evidence of intracranial mass or acute infarct. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, mastoid air cells, and scalp soft tissues are grossly unremarkable. There is a small left maxillary sinus retention cyst.
