Acute or chronic inflammation of gallbladder. Murphy sign: inspiratory arrest on RUQ palpation due to pain. Pain may radiate to right shoulder (due to irritation of phrenic nerve).􏰁ALP if bile duct becomes involved (eg, ascending cholangitis).

meningitis  To make sure, palpable Gallbladder is more in cholangiocarcinoma and Pancreatic Cancer? And if it were non-tender, could palpable gallbladder mean gallstones? +2  
yb_26  @meningitis, it is a Courvoisier sign of pancreatic adenocarcinoma: jaundice + palpable, nontender gallbladder +1

FA 2019 page 390. This patient is expressing symptoms of biliary colic due to neurohormonal activation by CCK after a fatty meal. The labs will be normal and ultrasound will show cholelithiasis. However, I think this can be confused with acalculous because it also presents with inspiratory arrest on RUQ palpation due to pain. Acalculous cholecystitis is seen in critically ill patients.
