Infundibulum sign – helpful in distinguishing an empty pituitary sella from a cystic lesion of the pituitary region. In the former, although the sella is enlarged, there is no mass and the pituitary infundibulum continues to traverse the enlarged sella to the residual pituitary at the floor. When a cystic mass is present however the infundibulum is displaced away.
