A 14-year-old girl initially presented to a pediatric gastroenterology office with a 1-month history of right upper quadrant abdominal pain, which radiated to the right shoulder and back. Her pain was worse after heavy meals and with deep breaths. She reported anorexia, fatigue, dyspnea while playing soccer, and a 5-pound weight loss. She denied any fevers, cough, or changes in her bowel habits.
