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.

Because adenomas of the pituitary are present in 10% to 20% of healthy individuals, the finding of incidental sellar lesions on computed tomography scanning or magnetic resonance imaging has become relatively common. Hyperfunctioning of such lesions can be excluded clinically and by hormonal screening.

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.

✓ Pituitary glands from 500 consecutive autopsies were reviewed and the findings correlated with clinical symptomatology. Occult pituitary adenomas were identified in 42 pituitary glands (8.5%). In only one case was a pituitary lesion clinically questioned, but specific hypophyseal function studies were not performed.

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 ...

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,

Radiosurgery for pituitary adenomas
Clinical Endocrinology, 2004The role of irradiation in the management of pituitary adenomas is not well defined. Nevertheless, patients with residual or recurrent tumours have been treated with conventional external-beam radiotherapy and more recently with highprecision stereotactic techniques of stereotactic radiosurgery (SRS) and stereotactic radiotherapy (SRT).

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.

Previous series of pediatric pituitary adenomas have been small and have not been analyzed by age group. We analyzed the frequency, manifestation, course, and biology of these tumors before, during, and after puberty in 136 children younger than 20 years old at surgery, identified by review of 2230 patients treated from 1969 to 1993.
