Ruptured mycotic pseudoaneurysm of the gastroduodenal artery presenting with hemoperitoneum and subcapsular liver hematoma.
We report a case of a patient with mycotic pseudoaneurysm of the gastroduodenal artery who presented with hemoperitoneum and subcapsular hematoma of the liver. The diagnosis was established with contrasted abdominal CT scanning. Visceral angiography was not needed. Prompt recognition and surgical intervention led to a favorable outcome. Pseudoaneurysm of visceral vessels is an uncommon disease process, and to our knowledge, this is the first reported case that has presented with free blood in the peritoneal cavity and beneath the liver capsule. This case may also represent a rare complication of therapeutic ERCP procedures. Mycotic aneurysm or pseudoaneurysm of visceral vessels may develop from bacteremia and its dissection or rupture should be suspected in patients presenting with sepsis and abdominal pain.
