Tuberous sclerosis [Q85.1] / Neoplasm of uncertain behavior of brain, unspecified [D43.2], Reason for Study: ^Reason: Evaluate SEGA, cortical tubers for change. Compare with previous History: Tuberous sclerosis. SEGA s/p cortical resection. Prior right frontal craniotomy with partial resection of anterior aspect of corpus callosum are redemonstrated. Multiple bihemispheric subcortical white matter T2/FLAIR high signal intensity lesions are again seen, unchanged since prior scan.Multiple subependymal nodules which most of them show susceptibility artifacts indicating calcifications are seen, unchanged.Enhancing lesions one on the right side foramen of Monroe, another on the left side foramen of Monroe and the other on the left lateral ventricular ependymal surface are seen, no significant interval change since prior scan.Calcified lesions on bilateral cerebellar hemispheres do not show any interval change since prior scan. The ventricles size appears to be stable since prior scan.Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
Known Tuberous Sclerosis patient with prior right frontal craniotomy for the resection of anterior corpus callosum lesion.No significant interval change of multiple cortical tubers and subependymal nodules as well as SEGAs since prior scan.Ventricle size also appears to be stable.
