Adrenal insufficiency due to bilateral adrenal hemorrhage is a rare but potentially life-threatening postoperative complication. The difficulty lies in making a timely diagnosis, as the symptoms are often unspecific and similar to those presented by other, more common postoperative complications. We report the case of a 71-year-old patient presenting bilateral adrenal hemorrhage following an otherwise uncomplicated low anterior rectum resection for a villous adenoma of the middle rectum.
