This is a male patient with past medical history of hypertension (HTN). He presented to the emergency department (ED) with complaints of abdominal/epigastric pain, fever and nausea and vomiting for a couple of days. The pain radiated to the right upper quadrant (RUQ). The patient had a sonogram at an urgent care center with findings of gallstones. Exam revealed the abdomen to be soft with RUQ tenderness and Murphy's sign. No guarding or rebound was noted. The patient was afebrile. His white blood cell count was 15.88.  An abdominal ultrasound was performed that showed distended gall bladder containing a calculus. The wall was mildly thickened with a small amount of pericholecystic fluid. There was also a positive sonographic Murphy's sign with the findings compatible with acute cholecystitis. The plan was to admit to surgery and underwent an uneventful laparoscopic cholecystectomy. He was treated with intravenous antibiotics and his diet was advanced as tolerated. He was medically stable and discharged home.
