Complications and expected imaging findings after endoscopic retrograde cholangiopancreatography

Figure 7 Cholecystitis. A and B: Axial (A) and sagittal (B) contrast-enhanced computed tomography images showed findings consistent with post-endoscopic retrograde cholangiopancreatography cholecystitis in a 33-year-old female patient who presented 10 days after endoscopic retrograde cholangiopancreatography with abdominal pain, nausea, and a positive Murphy’s sign. The patient’s laboratory results revealed elevated levels of aspartate aminotransferase, alanine aminotransferase, and acute phase reactants. Imaging features included gallbladder wall thickening, increased mucosal enhancement (yellow arrows), and stranding in the pericholecystic fat (blue arrow).
