The disorder of multiple cranial nerve palsies without spinal cord involvement is referred to as polyneuritis cranialis (PC) and is rare. It is thought to be an acute post-infective polyneuropathy or a variant of Guillain-Barré syndrome. Electrophysiological evidence of demyelination has been reported, but no radiological abnormalities of the affected cranial nerves have been noted. We report a case of PC where contrast enhanced magnetic resonance imaging (MRI) showed enhancement of the peripheral segments of the oculomotor and abducens nerves. This case illustrates the utility of MRI in the assessment of cranial nerve palsies.
