Case 2.A, Axial T2- and, B, T1-weighted MR images obtained 3 years after involved field radiation therapy at 3 years of age for a posterior fossa ependymoma showing a large hemorrhagic, lobulated lesion of mixed signal intensity (white arrow) in left cerebellar hemisphere and vermis. Two more small cavernomas (black arrowheads) are seen in the right cerebellum. Postoperative changes (black arrow) are noted in the right cerebellum.C, Axial T2‐weighted MR image shows an area of blooming due to another small cavernoma (black arrow) in the right temporo-occipital region.
