A Black woman in her early 70s with a history of coronary artery disease after coronary artery bypass operations, hypertension, and colon polyps presented to oculoplastic surgery with 1 week of progressive right-sided proptosis and headache, described as severe pain radiating to the back of her head. This was associated with right eyelid ptosis and blurry vision. Prior to presentation, an outside ophthalmologist treated her with 1 week of oral prednisone, 20 mg/d, for presumed orbital inflammation with no improvement. She denied additional symptoms. Notably, she described headache and sudden vision loss in the right eye after coronary artery bypass grafting 1 year ago for several days before spontaneous improvement with incomplete resolution. Personal and family histories were negative for malignant neoplasm and autoimmune disease.
