Pediatric Pituitary Tumors

Neurosurgery, 1991
Abstract This retrospective review of pediatric patients with pituitary tumors causing onset of symptoms by 17 years of age was done to define their pathological distribution, clinical presentation, treatment, and prognosis. Eighteen patients were evaluated and treated from 1979 to 1989.

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 hyperplasia mimicking pituitary tumor

Surgical Neurology, 1994
Reactive 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.

Diagnosis of Pituitary Tumors

Endocrinology and Metabolism Clinics of North America, 1988
In the last two decades, significant strides have been made in the diagnosis and management of pituitary tumors. The identification, isolation, and characterization of the anterior pituitary hormones, the developments of sensitive and specific radioimmunoassays, and the significant advances in neuroradiologic, neurosurgical, and pathologic techniques ...

Diagnosis and Management of Pituitary Adenomas: A Review.

Journal of the American Medical Association (JAMA), 2023
Importance Pituitary adenomas are neoplasms of the pituitary adenohypophyseal cell lineage and include functioning tumors, characterized by the secretion of pituitary hormones, and nonfunctioning tumors.

Pituitary tumors and pregnancy

Growth Hormone & IGF Research, 2003
Tumors vary in how they affect pregnancy depending upon the hormone secreted. Some hormone oversecretion syndromes must be controlled to allow pregnancy to proceed without undue maternal and fetal morbidity (Cushing's disease and hyperthyroidism) whereas treatment during pregnancy for other tumors is not necessary.

Angiogenesis and Pituitary Tumors

Seminars in Ophthalmology, 2009
Pituitary adenomas often first manifest through visual symptoms. They are typically slow-growing and histologically benign tumors, but can become clinically destructive, invade adjacent structures, and recur after treatment. Unlike many other tumors that become aggressive and appear to depend upon angiogenesis in the process, pituitary adenomas tend to

PATHOGENESIS OF PITUITARY TUMORS

Endocrinology and Metabolism Clinics of North America, 1999
Pituitary adenomas may hypersecrete hormones (including prolactin, growth hormone and adrenocorticotropic hormone, and rarely follicle-stimulating hormone, luteinizing hormone or TSH) or may be nonfunctional. Despite their high prevalence in the general population, these tumors are invariably benign and exhibit features of differentiated pituitary cell

Pituitary tumors in childhood

Current Opinion in Endocrinology, Diabetes & Obesity, 2012
This review focuses on recently published literature on pituitary tumors in children with special focus on craniopharyngioma and prolactinoma. Although most pituitary masses are benign neoplasms, they are associated with high morbidity and mortality related to their proximity to vital neurologic structures including the optic chiasm, hypophysis and ...

Nonfunctioning Pituitary Tumors and Pituitary Incidentalomas

Endocrinology and Metabolism Clinics of North America, 2008
Clinically 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.
