Whitehead, David Zander, Amanda CoreyAbstractNeuroendocrine dysfunction includes suspected hyper- and hypofunction of the pituitary gland. Causative lesions may include primary masses of the pituitary such as pituitary microadenomas and macroadenomas, as well as extrinsic masses, typically centered in the suprasellar cistern. Clinical syndromes related to hormonal dysfunction can be caused by excessive hormonal secretion or by inhibited secretion due to mass effect upon elements of the hypothalamic-pituitary axis. Additionally, complications such as hemorrhage may be seen in the setting of an underlying mass and can result in hormonal dysfunction. MRI with high-resolution protocols is the best first-line test to evaluate the sella turcica and parasellar region. CT provides complementary information regarding bony anatomy, and may be appropriate as a first-line test in certain instances, but it provides less detail and lesion characterization when compared to MRI.The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions...
