title: High-field MR imaging of superficial siderosis of the central nervous system.
abstract: A case of superficial siderosis of the central nervous system secondary to bleeding from an ependymoma is presented. High-field magnetic resonance imaging showed marginal hypointensity of the cervical cord, medulla oblongata, pons, mesencephalon, anterior cerebellar and basal cerebral surfaces, and cranial nerves (II, V, VIII). These findings were evident in the T2 weighted images.
