In 46 patients subjectcd to laparotomy for suspected of the primary liver cancer, 4 patients(9 per cent)had false-positive preoperative diagnosis. Of 4 patients without liver cancer, 2 had false-positive angiogram and 2 had false-positive CT. Of 2 patients with false-positive angiogram, one patient had the gastric wall stain which was similar to the pattern of liver cancer. The gastric wall stain was originated from the accessory left gastric artery which branches off from the left hepatic artery.
