 There are multiple partially enhancing subependymal nodular lesions along the margins of both lateral ventricles. The largest is in the anterior horn of the right lateral ventricle near the right foreman of Monro that measures 10 x 10 mm in transaxial view. There is also a lesion in the anterior horn of the left lateral ventricle near the left foreman of Monro that measures 8 x 7 mm in transaxial view. These nodules demonstrate susceptibility, representing mineralization.There are multiple scattered cortical and subcortical tubers with high T2/FLAIR intensity and with subtle intrinsic T1 hyperintensity on fat-suppressed post-contrast images. The lateral ventricles are mildly prominent, which is nonspecific.There is partial opacification of the paranasal sinuses. Trace fluid is seen in the mastoids.
Multiple subependymal nodules along the margins of the lateral ventricles including ones at the foramen of Monro, with multiple scattered cortical and subcortical tubers, consistent with known diagnosis of tuberous sclerosis.
