Imaging of the pituitary and sella turcica.
The pituitary gland is housed in the sella turcica and has vital endocrinologic functions. It lies in close proximity to numerous vital structures, including the optic chiasm, sphenoid sinus, cavernous sinus and hypothalamus. An understanding of the function, anatomy and embryology of the pituitary gland and its surrounding structures is vital to understanding its normal appearance, as well as in evaluating the broad spectrum of pathology that can involve the pituitary gland. Imaging of pathology in the sellar region, including pituitary adenomas, meningiomas, craniopharyngiomas and aneurysms, plays an important role in guiding treatment decisions. Modern imaging techniques are also important in evaluating the pituitary gland after surgery.
