Introduction
Celiac artery compression syndrome (CACS) is a rare disorder
characterized by chronic epigastric pain due to celiac artery
compression by median arcuate ligament overgrowth.1This syndrome is also known as median arcuate ligament syndrome or
Dunbar syndrome. Its diagnosis requires confirmation of celiac artery
stenosis, exclusion of other diseases, and characteristic symptoms. It
is associated with visceral aneurysms and dissection, involving the
celiac, mesenteric, and pancreaticoduodenal arteries.2,
3 The mortality rate for ruptured abdominal aneurysms is high, and
early detection and treatment are critical.4 Herein,
we report a case of a 56-year-old Japanese woman with sudden epigastric
pain, who was diagnosed with acute retroperitoneal hemorrhage secondary
to isolated posterior inferior pancreaticoduodenal artery (PIPDA)
dissection, accompanied by CACS.
