The posterior lobe the neural lobe or neurohypophysis of the pituitary gland is not, despite its name, a true gland.

Adenoma volumes ranged between 0. Although pituitary tumors arise as benign monoclonal neoplasms, genetic alterations have not readily been identified in these adenomas. These results show that p53 and ras gene mutations are not common events in the pathogenesis of acromegaly and nonsecretory tumors.

The anatomy of this structure causes pressure on it to produce a defect in the temporal visual field on both sides, a condition called bitemporal hemianopsia. The patient was discharged under treatment with corticosteroids and desmopressin.

The authors present the results of proton therapy in 59 patients with different hypophyseal adenomas. Although a large number of genes has been screened for mutations, only few genetic abnormalities have been found in pituitary tumors such as allelic deletion of chromosome 11q13 where the MEN-1 gene has been localised, and mutations in the gene encoding the alpha subunit of the stimulatory Gs and Gi2 protein.
