Conventional angiography with celiac injection (A) demonstrating a classic hepatic arterial anatomy, and one with SMA injection (B) showing an ARHA originating from the proximal SMA. MDCT showing the CHA arising from the CA (C), and an ARHA originating from the SMA, traveling behind the pancreatic head (D). ARHA: Accessory right hepatic artery; CHA: Common hepatic artery; SA: Splenic artery; LGA: Left gastric artery; RHA: Right hepatic artery; LHA: Left hepatic artery; SMA: Superior mesenteric artery; AA: Abdominal aorta; CA: Celiac axis.
