title: MRI in the differential diagnosis of a sellar mass.
abstract: Whilst pituitary adenomas are the commonest cause of a sellar mass, there are a number of other neoplastic, infectious, inflammatory, developmental and vascular aetiologies that should be considered by the radiologist. We discuss and illustrate these lesions and indicate the various magnetic resonance imaging features that are helpful in formulating an appropriate differential diagnosis.
