Pituitary Tumor

Overview is a group from the anterior and posterior cranial pharynx and tubular epithelial cells in the residual tumor. Pituitary tumors account for about intracranial tumors 10%, the tumor before leaf accounted for the majority of adenomas, from the posterior lobe were rare. Multiple intracranial metastases can be involved pituitary, with the identification of the pituitary tumor. Pathology Disease Cause It is not yet entirely clear. Symptoms of a hormone secretion syndrome : excessive hormone secretion syndrome, such as excessive growth hormone cause acromegaly; hormone secretion were less non-functional when the group increased tumor and normal pituitary tissue damage, reduction in gonadotropin secretion and amenorrhea, infertility or impotence often the earliest occurrence of styles. 2 oppression pituitary tumor tissues around with the group : to stimulate nerve fibers with a headache, was continuing headache; Optic nerve, and the optic chiasm compression beam patients with visual impairment, visual field defect, and fundus changes; Other compression group. Inspection is a skull X-ray film Sella said increasing deformation, saddle underneath collapse, a double bottom, saddle back erected thinning backwards, Osteoporosis often absorb damage; SERIES pituitary brain tissue density above; 3 Magnetic resonance imaging (MRI) to the pituitary soft tissue superior resolution CT, CT can compensate for the deficiencies; four gas brain and cerebral angiography. Treatment of surgery and radiation therapy with drug treatment. Individual cases for the choice depended on the nature of tumor, size, compression and the surrounding tissue and erosion of pituitary function, systemic illness such specific conditions.
