A 44-year-old man is referred by his optometrist to a retina specialist for a month of upper-left blurry vision and faded color. A visual field test shows a temporal and superior defect OS and nonspecific change OD. Two days prior to a scheduled MRI, he experiences sudden, excruciating holocranial headache with photophobia and is taken to an ER. MRI brain with contrast shows a pituitary mass with hemorrhage. He is admitted for emergent neurosurgical intervention and found to have central hypoadrenalism, hypothyroidism, and possible diabetes insipidus.
