 Basic findings indicative of submucosal tumors of the stomach were discussed from a radiological point of view. On X-ray diagnosis, there were four important features to be observed ; the surface, the margin of the tumor, bridging folds and central depression. The surface of submucosal tumors is usually shown as very smooth because such tumors are covered with normal gastric mucosa. The gradually elevated tumors show obscure margins of radiolucent shadows. Yamada's classification is available for the site of submucosal tumors of the stomach but it is impossible for it to diagnose exogastric tumors. Bridging folds considered as the most characteristic finding of submucosal tumors can be recognized not only in cases of submucosal tumors but also in other diseases. Central depression of the tumors was formed as they developed into bigger tumors and were suspected of being malignant tumors. It was also important to discuss the size, the location and the rigidity of tumors. By combining such radiological findings of submucosal tumors we still have to discuss always whether the tumors are epithelial or non-epithelial and whether they are benign or malignant.
