Axial T2 MRI without contrast of the brain (left) shows three rounded low intensity subependymal lesions along the lateral aspect of the left lateral ventricle. Axial FLAIR MRI image without contrast of the brain (right) shows multiple bilateral poorly defined hyperintense areas located just beneath the cortex of the brain.
The diagnosis was multiple subependymal nodules and subcortical tubers in tuberous sclerosis.
