A relatively rare case of gastric lipoma, in which computed tomography (CT) was proved useful for diagnosis is reported, with a review of 180 cases of gastric lipoma in Japan. The patients was 47-year-old man. A gastric submucosal tumor had been detected in an upper gastrointestinal series and endoscopic examination about 3 years before he was admitted to our hospital for further examination of the tumor, which was increasing in size. An upper gastrointestinal series and endoscopic examination revealed a submucosal tumor in the posterior wall of the stomach body. Diagnosis from the biopsy of the submucosal tumor was not possible, however a low CT numbr suggested that the tumor was a lipoma. The tumor was surgically extirpated. Histological examination showed that the tumor was a gastric lipoma composed of mature adipose cells. The results of this case suggest that a CT scan can help diagnose gastric lipoma.
