Endosonographic Findings and the Natural Course of Chronic Gastric Anisakiasis: A Single-Center Experience

Figure 2

A representative case of chronic gastric anisakiasis (case 11). (a) Initial endoscopy shows a subepithelial tumor-like lesion in the lesser curvature of the gastric midbody. (b) On endoscopic ultrasonography, the lesion is a heterogeneously hypoechoic lesion in the submucosal and muscularis propria layers. Hyperechoic tubular structures are seen inside the lesion (arrow). (c) Endoscopic biopsy reveals increased eosinophil infiltration (hematoxylin and eosin stain, ×400). (d) Follow-up endoscopy performed 6 months later shows that the lesion has subsided completely.
