Cholecystitis (jaundice) than in calculous cholecystitis. Ultrasonography or computed tomography often shows an immobile, enlarged gallbladder. Treatment involves immediate antibiotics and cholecystectomy within 24–72 hours. Chronic cholecystitis occurs after repeated episodes of acute cholecystitis and is almost always due to gallstones. Chronic cholecystitis may be asymptomatic, may present as a more severe case of acute cholecystitis, or may lead to a number of complications such as gangrene, perforation, or fistula formation. Xanthogranulomatous cholecystitis (XGC) is a rare form of chronic cholecystitis which mimics gallbladder cancer although it is not cancerous. It was first reported in the medical literature in 1976 by
Cholecystitis in the area below the right scapula, can be a symptom of acute cholecystitis. In someone suspected of having cholecystitis, blood tests are performed for markers of inflammation (e.g. complete blood count, C-reactive protein), as well as bilirubin levels in order to assess for bile duct blockage. Complete blood count typically shows an increased white blood count (12,000–15,000/mcL). C-reactive protein is usually elevated although not commonly measured in the United States. Bilirubin levels are often mildly elevated (1–4 mg/dL). If bilirubin levels are more significantly elevated, alternate or additional diagnoses should be considered such as gallstone blocking the common bile
