Pituitary tumour presenting with trigeminal neuralgia as an isolated symptom

Abstract

Invasion of the cavernous sinus by pituitary adenoma may cause involvement of cranial nerves III, IV,V and VI. However, trigeminal neuralgia as an isolated, initial symptom is very unusual. A patient with a pituitary adenoma, who had intractable trigeminal neuralgia as the only complaint which resolved following surgical removal is presented.
