Abdominal apoplexy was reported by Barber in 1909, and the occurrence rate of the apoplexy is known to be quite rare, but the mortality is high if untreated. We report an unusual case of abdominal apoplexy due to spontaneous rupture of gastric artery. A male patient in his fifth decade with recently diagnosed liver cirrhosis history arrived to the emergency department with severe abdominal pain, which led to abdominal computer tomography indicating spontaneous rupture of gastric artery. Celiac angiogram and embolization were conducted, and exploratory laparotomy was followed. The outcome of the patient was poor, and he died on the second day of admission. As in our case, the mortality can be high, so prompt restoration of circulation volume and early diagnosis should be made in similar cases.
