Surprise Finding at Endoscopic Retrograde Cholangiopancreatography

A 47-year-old woman was admitted with right upper-quadrant pain, radiating to her back, with nausea and fever. She was known to have had gallstones and had undergone open cholecystectomy 9 years earlier. She developed epilepsy after an intracerebral hemorrhage at the age of 22, for which she was on treatment with phenytoin and carbamazepine, and had mild asthma.
