Tuberous sclerosis [Q85.1], Reason for Study: ^Reason: patient with TSC follow up study History: TSC, SEGAS Multifocal bihemispheric subcortical T2/FALIR high signal intensity lesions are again demonstrated, unchanged since prior scan.Multiple subependymal nodules some with susceptibility artifacts are unchanged since prior scan.There are enhancing lesions located at the level of foramen of Monroe bilaterally. Specifically, the right side lesion is measured about 18mm (AP) and 10.6mm (RL) which is unchanged since prior scan (17mm x 10mm). The other lesion on the left side was measured about 17.3mm (AP) x 7.6mm (RL), again unchanged since prior scan 17.5mm x 7.4mm. However, comparing to 2011 scan, both lesions show slightly increased in size (right:16mm x 10mm, left:12mm x 7mm).There is no evidence of ventriculomegaly.There is no evidence of acute ischemic or hemorrhagic lesion.The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. No significant interval change of subcortical tubers, calcified subependymal nodules and enhancing nodules at bilateral foramen of Monroe level since prior scan performed on Jul 1 2015.2. However, both enhancing lesions appear to be slightly increased in size since 2011 as described above.3. No evidence of hydrocephalus.4. No acute ischemic or hemorrhagic lesion.
