Endoscopic ultrasonography findings of visualized submucosal tumor. A: Endoscopy shows 10-mm shows submucosal tumor (SMT) in lesser curvature of lower corpus of stomach; B: Narrow-band endoscopic imaging SMT covered by normal gastric mucosa; C: Endoscopic submucosal dissection (ESD) for SMT; D: Stomach ulceration five days after ESD; E: Endoscopic ultrasonography (EUS) findings show internally isoechoic, homogeneous sub-mucosal tumor mainly localized within second and third layers, whereas first and fourth layers are preserved; F: Acoustic shadowing of hyperechoic foci inside lesion is consistent with calcifications. Fourth layer is obvious.
