Hepatobiliary scan with delayed gallbladder visualization in a case of acute appendicitis.
A 40-year-old woman presented with acute epigastric pain with vomiting. Within 24 hours, the pain spread to the right periumbilical region. Tc-99m disofenin hepatobiliary scan failed to demonstrate the gallbladder on a 60-minute view. The presumative diagnosis of acute cholecystitis was thought to be confirmed on this basis by the patient's physicians. However, a 75-minute view demonstrated filling of the gallbladder. In hepatobiliary scanning for acute abdominal pain, delayed views (2 to 24 hours) are recommended when the gallbladder is not visualized on the 60-minute view. If the gallbladder is visualized, cystic duct obstruction can be excluded and diagnoses such as pancreatitis, acalculous cholecystitis, and acute appendicitis should be investigated.
