PITUITARY APOPLEXY - A CAUSE FOR PAINFUL 3RD NERVE PALSY

A series of cases of painful third nerve palsy due to pituitary apoplexy is reported to highlight this less recognized cause. Four cases presented with sudden onset of headache associated with an oculomotor nerve palsy. CT scan showed assymmetrical expansion of a pituitary adenoma into the corresponding cavernous sinus in each patient. All palsies recovered spontaneously post transsphenoidal resection of the tumour. The problems associated with the diagnosis of pituitary apoplexy are discussed and the vital role of positive radiological findings is emphasized. © 1990 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
