title: Is magnetic resonance imaging more sensitive than computed tomography in the location of corticotropin secreting pituitary adenomas?
abstract: Two cases of pituitary-dependent Cushing's syndrome are described in which the computed tomography (CT) examination was negative; as the hormone dynamic investigations were directed towards the presence of corticotropin (ACTH) secreting pituitary formations, magnetic resonance imaging (MRI) of the pituitary was performed, which evidenced the presence of such lesions; subsequent neurosurgery confirmed in both cases the location indicated by MRI. In conclusion, the higher sensitivity of MRI compared to CT in the diagnosis of ACTH secreting pituitary adenomas can be noted.
