Three cases of pituitary abscess are presented. In spite of improvemen
ts in radiological evaluation, preoperative diagnosis of pituitary abs
cess is quite difficult and definite preoperative diagnosis is rare in
the literature. In our three cases, diagnosis was made postoperativel
y. Pituitary abscesses are associated with high mortality and morbidit
y. When first suspected, prompt antibiotic therapy should be considere
d. Early operative drainage seems to be an important factor in decreas
ing this high mortality and morbidity.
