Increased use of MRI technology has resulted in a surprising medical dilemma. Scans used for early detection of tumors often reveal benign internal growths that would otherwise have gone undetected, called incidentalomas. This creates the problem of determining whether the growths are harmful without performing needless surgeries. Assume that you have found a pituitary incidentaloma in one of your patients.
