Nucl. Med. Technol.2016 Dec 01; 44 AB - We present a case study of a 56-y-old man who was admitted with acute abdominal pain and was found to have retroperitoneal hematoma from a ruptured duodenal aneurysm. 99mTc-diisopropyliminodiacetic acid cholescintigraphy showed incidental absent transit of radiotracer into the distal duodenum and severe enterogastric reflux, thought to be secondary to duodenal obstruction from the hematoma. Findings were confirmed on esophagogastroduodenoscopy, and the patient improved after subsequent gastrojejunostomy.
