RT Journal A1 McKee TI T1 IMage of the month—quiz case JF Archives of Surgery JO Archives of Surgery YR 2012 FD February 1 VO 147 IS 2 SP 195 OP 195 DO 10.1001/archsurg.2011.642 UL http://dx.doi.org/10.1001/archsurg.2011.642 AB A 71-year-old woman had a sudden onset of what she described as a “tummy ache” at 9 PM the evening prior to admission to the hospital. The midabdominal discomfort progressively worsened to severe abdominal pain with associated back pain. She had vomiting without hematemesis. There was no history of hematochezia or melena, and she had a normal bowel movement the previous day. She was receiving treatment with warfarin sodium for a history of atrial fibrillation. Formerly weighing 144.0 kg, she attributed a weight loss of 60.8 kg over 8 years to exercise and a diet plan that included a lot of fiber. Although she had diverticulosis noted on a colonoscopy a few years ago, she had never had an abdominal operation. Her family history included coronary artery disease and cerebrovascular accident.
