The Radiology of Pituitary Adenomas
Endocrinology and Metabolism Clinics of North America, 1984The radiologic management of pituitary adenomas has changed considerably over the last decade. With the development of sophisticated new technologies, diagnostic testing has evolved from pneumoencephalography to pluridirectional tomography, computed tomography, and currently magnetic resonance imaging.

Neurosurgical Review, 1985
Based on 880 pituitary adenomas operated upon between 1972 and 1982 the diagnostic and therapeutical strategy in recurrences is discussed. The incidence of reoperations was 7.75%, 3.7% in hormonally inactive and 4.1% in hormonally active recurrences.

The pathogenesis of pituitary adenomas
Clinical Endocrinology, 1993The pituitary gland influences osmoregulation, growth, lactation, the immune system and parturition, and is respon- sible for regulating thyroid, adrenal and gonadal function. During lactation and in response to conditions such as hypothyroidism and hypoadrenalism, specific cell types in the pituitary undergo hypertrophy.

American Journal of Clinical Oncology, 2010
Pituitary adenomas comprise approximately 10% to 20% of all central nervous system neoplasms whereas autopsy series have suggested that the incidence of pituitary adenoma in the general population may approach 25%. Several treatment modalities are used in the treatment of pituitary adenomas, including observation, surgery, medical intervention, and ...

Endocrine, 2013
Double pituitary adenomas represent up to 2.6 % of pituitary adenomas in large surgical series and up to 3.3 % of patients with Cushing's disease have been found to have double or multiple pituitary adenomas. We report the case of a 60-year-old male patient whose medical history began in 2002 with erectile dysfunction; hyperprolactinemia was found and ...

The immunophenotype of pituitary adenomas
Endocrine Pathology, 1996Although the production of pituitary hormones by adenohypophysial tumors has been studied extensively, an examination of the immunophenotype of pituitary adenomas using a broad spectrum of antibodies has not been previously investigated. We studied 23 pituitary adenomas using a large panel of antibodies to determine if these tumors exhibited a common ...

Autophagy and Pituitary Adenoma
2020Pituitary adenomas (PAs) are common, benign intracranial tumors that are usually effectively controlled with surgery, pharmacotherapy or radiotherapy. Some PAs against which conventional treatment is ineffective are great clinical challenges at present. Autophagy is a widespread physiological process in cells.

Calcifications in pituitary adenomas
Surgical Neurology, 1981In a surgical series of 755 pituitary adenomas, 51 cases (6.75%) showed intratumoral calcifications on microscopic examination and 13 of these were visible on roentgenographic examination (1.72%). Thirty-eight of these 51 cases were prolactinomas, the highest incidence being in male patients. There was no correlation between age, sex, levels of hormone,

Multihormonal Pituitary Adenomas
Hormone Research, 200866 pituitary tumors detected at autopsy were investigated for the presence of corticotropin, β-lipotrophin, growth hormone, prolactin, thyrotropin and gonadotropins by immunocytochemistry. 56 tumors contained hormone-producing cells; 45 were found to contain 2 or more hormones.

Radiosurgery for Pituitary Adenomas
2007Stereotactic radiosurgery has been used to manage patients with pituitary adenomas for over 30 years. Numerous studies have documented that more than 95% of pituitary adenoma patients have either tumor shrinkage or stabilization after radiosurgery.
