22 years Male (DOB:10/14/1993)Reason: h/o demyelination, infantile spasms History: altered mental statusPROVIDER/ATTENDING NAME: NEIL H HYMAN NEIL H HYMAN There is T2 and FLAIR ill-defined signal hyperintensity surrounding the trigone and occipital horn of the right lateral ventricle. Air is associated FLAIR leptomeningeal signal hyperintensity along the surface of the right temporal lobe extending to the right inferior parietal lobule.. There is no associated contrast enhancement. These findings have not changed substantially when compared to the previous exam.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
There are vague signal changes present involving predominantly right temporal lobe white matter and and to a lesser degree gray matter especially adjacent and lateral to the temporal horn and trigone of the right lateral ventricle. Some patchy signal changes are also present in the right temporal lobe gray matter. These are nonspecific findings. These findings are stable compared to the previous exam.
