We present a rare case of delayed pseudoaneurysm formation in the proper hepatic artery without hepatic injury following blunt trauma. The patient was a 42-year-old man who was injured by a fall from height. Initial computed tomography (CT) showed no hepatic injury, but vascular wall irregularity was noted from the origin of the proper hepatic artery to left hepatic artery, and a small hematoma was observed in the hepatoduodenal ligament. Follow-up CT conducted three days post-injury showed no pseudoaneurysms in the hepatic arteries. However, pseudoaneurysms in the proper hepatic artery and left hepatic artery were incidentally confirmed by CT at two months post-injury. The patient was treated immediately with coil embolization, and his postoperative course was uneventful. Extrahepatic vascular injury should be considered when initial abdominal CT shows hematoma in the hepatoduodenal ligament and vascular wall irregularity.
