Sellar masses may present with an impairment of pituitary function (hypopituitarism), hormone hypersecretion (prolactinoma, acromegaly, glucocorticoid excess) or neurological symptoms (visual impairment, headache). An increasing number of them is discovered as an incidentaloma. Among the various entities, benign pituitary adenomas and cystic lesions are most frequently encountered. The work-up includes a laboratory evaluation for hormone hyper- or hyposecretion and an MRI of the pituitary gland. If the optic chiasm is compromised, a visual field examination is mandatory. Except for prolactinomas, symptomatic sellar masses are usually resected via an endoscopic transsphenoidal approach. If a total resection is not feasible because of the invasion of surrounding structures, debulking to relieve pressure from the optic chiasm is the primary goal and radiotherapy may be considered. Residual hormone excess can be treated medically. In the early postoperative period special attention to the development and treatment of disordered body water homeostasis and hypopituitarism is crucial. Interdisciplinary work-up and decision making are of utmost importance and will offer the best management. [ABSTRACT FROM AUTHOR]

Pituitary adenomas (PA) are benign neoplasms originating from parenchymal cells of the anterior pituitary. Tumor mass effect can cause headaches, visual deficits by compression of the optic chiasm, and partial or complete hypopituitarism. Hormone secreting PA can cause several forms of specific syndromes such as Cushing's disease or acromegaly depending on the type of hormone. Endoscopic transsphenoidal resection is the preferred treatment option for most symptomatic or growing PA. Nowadays techniques like high definition intraoperative MRI can assist the surgeon in his goal of maximal safe resection. An exception are prolactinomas which can usually be treated medically with dopamine agonists. Therapy of PA is complex and should be managed in a high-volume center with an interdisciplinary team approach including neurosurgeons and endocrinologists. [ABSTRACT FROM AUTHOR]
