Fig. 4B —Misdiagnosis of early gastric cancer (EGC) in 47-year-old man
without gastric cancer. Virtual gastroscopy image shows similar superficially
elevated (arrows) and depressed (arrowhead) lesion located
in greater curvature side of gastric mid body. Virtual gastroscopy also shows
converging fold changes. This finding suggests EGC; all three observers
diagnosed as EGC, but gastroscopy showed no abnormal mucosal change. All
observers might have confused giant fold in greater curvature of stomach with
enhanced tumor mass.
