Tuberous sclerosis [Q85.1], Reason for Study: ^Reason: evaluate cortical tubers, SEN, SEGA History: tuberous sclerosis Multifocal bihemispheric cortical tubers involving bilateral frontal and parietal lobes (left greater than right) appear to be stable without evidence of enhancement, thus unchanged since prior scan.There are two susceptibility lesions on the left lateral ventricle and both show evidence of enhancement; one on the ependymal surface of the left lateral ventricle frontal horn, caudate head area and another on the ependymal surface of the left side foramen of Monroe area. Both were seen on prior scans and the both nodules showed enhancement (the former greater than the latter) on prior scans. Thus, unchanged MR characteristics and size since prior scan. The right frontal lobe DVA is again seen, unchanged since prior scan.No evidence of acute ischemic or hemorrhagic lesion.The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. Evidence of bilateral frontal and right temporal craniotomy, unchanged since prior scan.The paranasal sinuses and mastoid air cells are clear.
Unchanged multifocal cortical tubers as described above.Stable size and MR characteristics including enhancement pattern of two subependymal nodules on the ependymal surface of the left lateral ventricle frontal horn.
