Figures & Data

Gastrointestinal anisakiasis is an uncommon zoonotic parasitic infection caused by consumption of raw or undercooked seafood infected with nematodes of genus Anisakis. A 44-year-old woman presented to our emergency department with acute upper abdominal pain 14 h after ingestion of Mackerel sashimi. During physical examination, she was found to have tenderness in the epigastric region. Abdominal ultrasonography showed markedly and diffusely thickened walls from the pylorus to the gastric corpus, very smooth surfaces and low homogeneous internal echoes (Figure 1a). Emergency gastroscopy identified 12 mm and 14mm long larva of the nematode Anisakis simplex penetrating the inflamed body of the stomach (Figure 1b). Disinfestation rapidly resolved the patient's symptoms. Ultrasonography is useful to diagnosis gastric anisakiasis which shows a thickened wall [1,2].
