ABSTRACT Objective: To analyze the clinical, laboratory, and radiological findings and management of patients with clinical pituitary apoplexy and to screen for aryl hydrocarbon receptor-interacting protein (AIP) mutations. Subjects and methods: The clinical findings were collected from the medical records of consecutive sporadic pituitary adenoma patients with clinical apoplexy. Possible precipitating factors, laboratory data, magnetic resonance imaging (MRI) findings and treatment were also analyzed. Peripheral blood samples were obtained for DNA extraction from leukocytes, and the entire AIP coding region […]

Pituitary apoplexy is characterized by sudden increase in pituitary gland volume secondary to ischemia and/or necrosis, usually in a pituitary adenoma. Most cases occur during the 5th decade of life, predominantly in males and in previously unknown clinically non-functioning pituitary adenomas. There are some predisposing factors as arterial hypertension, anticoagulant therapy and major surgery. Clinical picture comprises headache, visual impairment, cranial nerve palsies and hypopituitarism. Most cases improve with both surgical and expectant management and the best approach in the […]

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 […]
