The patient had no headaches, no neuro-ophthalmologic symptoms, and no focal neurologic deficits. The presentation was slow and insidious. The patient received glucocorticoid and thyroid hormone replacement therapy, after which her clinical status improved substantially. Silent pituitary infarction after coronary artery bypass grafting has been reported previously in 3 male patients, but our current case is the first...Continue Reading
