Pituitary abscess-A case report.

Two hundred and five cases of pituitary lesion were treated in Tri-Service General Hospital up to March 1989. A case of pituitary abscess was diagnosed during operation. The primary clinical manifestations are consequent upon the pituitary dysfunction and the mass effect of the pituitary abscess. A pre-operative diagnosis of pituitary abscess is usually very difficult. Transsphenoidal drainage with an appropriate antibiotic coverage may provide an optimistic prognosis.
