1 Patient 4. Patient 4. A 39-year-old woman had a solid nonfunctioning pituitary adenoma without cyst or hematoma. She had no past or present headache. A, Coronal T1-weighted MR image showing the isointense tumor. B, Coronal T2-weighted MR image showing the mixed high signal intensity pituitary lesion. C, Coronal T2*-weighted GE image showing diffuse dark appearance of the adenoma. D, Photomicrograph showing hemorrhage in chromophobic adenoma (H&E stain, original magnification ×40). M.
