Male, 16 years old, with tuberous sclerosis, annual follow-up. Multiple scattered ill-defined cortical and subcortical T2 hyperintense lesions are redemonstrated without significant change. In addition, multiple small, intrinsically T1 hyperintense and perhaps minimally enhancing subependymal nodules are seen along the ventricular margins. These measure no more than 5 mm in size and are also unchanged.No new parenchymal lesions are detected. No evidence of edema or mass effect is seen. There are no findings to suggest acute intracranial hemorrhage or any abnormal extra-axial fluid collection. The ventricles are normal in size and morphology.A lobular cutaneous lesion along the right forehead is redemonstrated showing no significant interval change in size when compared to the immediate prior exam.
1.Multiple intracranial stigmata of tuberous sclerosis are redemonstrated without significant interval change.2.A cutaneous right forehead lesion is also unchanged.
