T1 with Gd shows cystic lesion in the cerebellum with strongly enhancing mural nodule (Hemangioblastoma). Another cystic lesion is seen in medulla oblongata, that also contains strongly enhancing mural nodule (arrow). This patient is known with Von Hippel Lindau syndrome and is known with multiple Hemangioblastomas also in the spinal cord and has previously been operated in the posterior fossa. Cystic wall rarely enhances - important in differential diagnosis.
