title: [Pituitary abscess simulating apoplexy].
abstract: A pituitary abscess is a rare pathology, but it must be considered when evaluating sellar masses, since its prognosis depends on surgical drainage and on the use of specific antibiotics. The main clinical manifestation is chronic headache, and it is not always associated with the identification of a site of infection, which diminishes the probability of including it in diagnostic hypotheses. The case is presented of a patient with a pituitary abscess and a previous history of adenoma that had been operated on, recent onset headache and acquired hypopituitarism whose initial diagnosis was pituitary apoplexy.
