case_images: Contrast-enhanced computed tomography (CT) showed no findings that were suggestive of aortic dissection or pancreatitis; however, local thickening of the anterior portion of the gastric wall was observed (Figure 1).

case_images: We suspected anisakiasis or gastric ulcer and performed an upper gastroscopy, which confirmed the presence of a single live anisakid nematode larva penetrating the gastric mucosa in the greater curvature of the lower body (Figure 2).
case_images: Endoscopic Anisakiasis removal. Anisakis larvae were removed endoscopically with forceps.
