Gadolinium enhancement of cauda equina: a new MR imaging finding in the radiculitic form of tick-borne encephalitis

S Marjelund et al. AJNR Am J Neuroradiol. 2006 May.

Abstract

Tick-borne encephalitis virus is an important human pathogen in Europe. The infection usually presents as meningitis, meningoencephalitis, or meningoencephalomyelitis and only rarely as symptoms of isolated myeloradiculitis. We describe the lumbar MR imaging finding in a 48-year-old man with serologically confirmed tick-borne encephalitis in which there was enhancement of the ventral surface of the conus and the anterior nerve roots from the T12 level extending along the length of the ventral cauda.

Axial 7-mm T2* image (A) at the level of conus medullaris shows normal finding. Gadolinium-enhanced 4-mm sagittal (B) and 5-mm axial (C) T1-weighted MR images show enhancement of the anterior nerve roots (arrow) at the level of conus medullaris. Coronal 5-mm T1 fat-saturated image shows enhancement of the nerve roots (arrows) up to level L5 (D).
