Figure 1 EUS features of gastric mesenchymal tumors. A: A gastric leiomyoma. The mass is homogenous and its echogenicity is similar to that of the surrounding normal muscle layer. It is 35 mm × 13 mm in size and a marginal halo is not observed; B: A gastric GIST with low risk potential. The mass is inhomogenous and its echogenicity is somewhat higher than that of the surrounding muscle layer. It is 25 mm × 18 mm in size. A marginal halo (arrow) and hyperechogenic spots are seen; C: A gastric GIST with high risk potential. The mass is inhomogenous and 82 mm × 76 mm in size. A marginal halo, hyperechogenic spots and irregular border (arrow head) are seen.
