A case of large gastrolithiasis passed spontanneously

A patient is 72 years old woman who complained of epigastric pain. Upper GI endoscopy performed, it found an ulcer in lesser cuveture and a lage gastric calculus which was about 5cm in the diameter. The patient was admitted in our hospital because of removal of gastric calculus. Abdominal CT findings showed the stone was 40×26×45mm within air density at the upper body of stomach. After Upper GI X-ray examination, the large stone passed spontaneously because it was solved by sodium hydrogen carbonate. Upper GI endoscopy was performed and it found a healing ulcer and no stone in the stomach. This case is very rare because we observed the passing spontaneously of the large gastric stone by endoscopy and CT scan.
