Evaluation of the pituitary gland is a frequently faced request. Accurate and thorough scrutiny of the sellar region is critical in neuroradiology practice, as detecting even the tiniest lesion can have a profound clinical impact. The purpose of our exhibit is to expand upon one commonly encountered category of sellar abnormality, the cystic pituitary lesion. We will discuss the defining clinical and imaging characteristics of each of the differential diagnoses using authentic cases from our institution.

Review of the anatomy of the sellar region as well as the relevant embryology and physiology of the pituitary gland. Description of the normal pituitary MRI signal characteristics and the differences that must be kept in mind when special populations, such as newborns and pregnant patients, are imaged. An illustrative discussion of the differential for cystic/partially cystic pituitary lesions will be presented, including pituitary adenoma, rathke cleft cyst, craniopharyngioma, arachnoid cyst, epidermoid cyst, and empty sella. The clinical presentations, unique imaging findings, and management options will be highlighted for each diagnosis. The typical sequences included in a sella MRI protocol, the role of dynamic contrast MRI, and other protocolling pearls will also be discussed.
