title: Differential diagnosis of pituitary tumors.
abstract: Many parasellar lesions may mimic pituitary adenomas clinically, endocrinologically, and radiologically. Certain patterns do lead suspicion toward the correct diagnosis, whereas in other cases the diagnosis may be difficult. For most of these lesions, the treatment of choice is different from that for a pituitary tumor, so correct diagnosis is of paramount importance. The presenting signs and symptoms as well as radiologic manifestations of parasellar tumors and conditions are discussed.
