Reason: patient with TS, assess for new findings History: increased seizure activity Multiple cortically based T2 and FLAIR hyperintense lesions are scattered in both hemispheres of the supratentorial brain. These are not as readily visible on the prior exam from 2013 and appear larger on the current exam. There is redemonstration of multiple subependymal nodules which were also present on the prior exam and are unchanged.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 demonstrate mucosal thickening. The visualized portions of the mastoid air cells are partially opacified. The visualized portions of the orbits are intact.
1.Since the previous exam cortical tubers are more conspicuous and larger than on the prior exam. In part this increase in conspicuity may be related to brain development in the interim.2.There is redemonstration of stigmata of a tubular sclerosis.
