Hemobilia in a child due to right hepatic artery pseudoaneurysm: multidetector-row computed tomography demonstration

We present a case of a 12-year-old boy who developed upper gastrointestinal bleeding in the form of hematemesis and melena 1 month after blunt trauma to liver. Computed tomography [CT] angiography with multidetector-row CT demonstrated pseudoaneurysm of right hepatic artery related to old liver laceration to be the cause of the bleeding. Pseudoaneurysm was resected using the roadmap provided by CT angiography findings

Post-cholecystectomy Mirizzi's syndrome: magnetic resonance cholangiopancreatography demonstration

A long cystic duct remnant may be found after laparoscopic cholecystectomy. Stone may form in the remnant cystic duct and can cause postcholecystectomy syndrome. Remnant cystic duct calculus may rarely result in postcholecystectomy Mirizzi's syndrome. Traditionally, Mirizzi's syndrome has been diagnosed with endoscopic retrograde cholangiopancreatography [ERCP] and treated with open surgery. We report a case of postcholecystectomy Mirizzi's syndrome that developed 3 years after laparoscopic cholecystectomy. A non-invasive diagnosis of Mirizzi's syndrome was made comprehensively by magnetic resonance cholangiopancreatography. Endoscopic stone removal was achieved successfully with ERCP without any complication
