Masa selar, no siempre un adenoma: presentación de 3 casos clínicos

Pituitary abscess is due to a severe and uncommon infection in the sella. It is difficult to diagnose due to varied and non-specific symptoms. A report is presented of 3 cases of pituitary abscess, which had the presence of pre-existing injuries in common. All were subjected to surgery, with aseptic abscesses found in 2 patients, and Aspergillus capsulatum was isolated in 1 patient. They showed good progress with medical treatment, but with sequelae of hypopituitarism. It is very important to consider the pituitary abscess in the differential diagnosis of the masses that are located in that region, as a timely diagnosis and proper treatment can be important for the prognosis of these patients.
