  • Look Inside

Trigeminal nerve dysfunction as a false localizing sign, although rare, is known to occur. A case of chor-oid plexus papilloma in the 4th ventricle with hemifa-cial numbness is presented.

A 24-year-old woman had been suffering from inter-mittent facial numbness on the left side for 3 months prior to admission. She noted no other symptoms.

Neurological examination disclosed marked papil-ledema, horizontal nystagmus on both lateral gazes and mild truncal ataxia.

CT scans showed a calcified mass lesion in the 4th ventricle on the midline extending into the left lateral recess.
