Pituitary apoplexy (PA) is a rare clinical syndrome caused by sudden hemorrhaging and/or infarction of the pituitary gland, generally within a pituitary adenoma. The main symptom is sudden-onset severe headache, associated with visual disorders or ocular palsy. Corticotropic deficiency may be life-threatening if left untreated. Computed tomography (CT)

Pituitary enlargement mimicking pituitary tumor
Journal of Neurosurgery, 1985✓ Primary hypothyroidism can result in reactive enlargement of the pituitary gland which is indistinguishable from primary pituitary lesions on computerized tomography (CT) scans. The presenting symptoms may be due to pituitary gland enlargement, as in two of the three cases reported here.

Pituitary carcinoma is a extremely rare and is characterized by a very poor prognosis. Even if at diagnosis the presence of metastases is required to define a pituitary carcinoma, the lesion was almost invariably diagnosed first as a benign pituitary tumor, that after a variable period of latency, ranging from few months to many years, changed its ...

Pituitary, 2001
In 1994, Zhang et al. of Rockefeller University in New York reported the first successful complementary DNA (cDNA) cloning of leptin by the positional cloning method. Leptin was identified as the gene of ob/ob mouse in genetic obesity syndromes. It has very strong food intake control, and body weight and energy expenditure.

Endocrinology and Metabolism Clinics of North America, 1997
Incidental pituitary masses are commonly found during CT and MR imaging performed for a variety of reasons. Screening for hormone oversecretion by these tumors seems to be warranted. Patients with lesions greater than 1 cm should be screened for hypopituitarism.

Pituitary hyperplasia mimicking pituitary tumor
Surgical Neurology, 1994Reactive enlargement of the pituitary gland in primary end organ failure may be indistinguishable from primary pituitary lesions in clinical presentation and on magnetic resonance imaging. The diagnosis of pituitary hyperplasia secondary to end organ failure must be based on endocrinologic investigations.

Pituitary siderosis: the dark side of the pituitary
The Lancet Diabetes & Endocrinology, 2016A 23-year-old woman with persistent secondary amenorrhoea, 2 years after completion of non-ovarian toxic chemotherapy for osteosarcoma, was referred from the oncologist for investigation. She had severe sicklecell disease, diagnosed at age 18 months, requiring frequent red blood cells, exchange transfusion treatments, and a splenectomy.

Nonfunctioning Pituitary Tumors and Pituitary Incidentalomas
Endocrinology and Metabolism Clinics of North America, 2008Clinically nonfunctioning adenomas (CNFAs) range from being completely asymptomatic, and therefore detected at autopsy or as incidental findings on head MRI or CT scans performed for other reasons, to causing significant hypothalamic/pituitary dysfunction and visual field compromise because of their large size.

Aggressive Pituitary Tumors or Localized Pituitary Carcinomas: Defining Pituitary Tumors
Expert Review of Endocrinology & Metabolism, 2016Pituitary tumors are common and exhibit a wide spectrum of hormonal, proliferative and invasive behaviors. Traditional classifications consider them malignant only when they exhibit metastasis. Patients who suffer morbidity and mortality from aggressive tumors classified as "adenomas" are denied support provided to patients with "cancers" and in many ...
