Magnetic resonance images of a patient suffering from subacute combined degeneration of spinal cord (SACD) before and after cobalamin substitution. a Before therapy: Sagittal and transversal T2-weighted images reveal an intraspinal hyper intensity of the dorsal cervical spinal cord (→) with no mass effect. No contrast enhancement of the lesion was found in T1-weighted images. b 5 months after the onset of cobalamin substitution: The hyper intensity completely disappeared. Known osteochondrosis and disc protrusion C5/6. In the sagittal view the transversal section plane is marked by a dotted line
