Abstract
A case of gastric anisakiasis due to the larva of Pseudoterranova decipiens was confirmed by gastroendoscopic examination in April 23, 1991. The patient, residing in Pusan, was a 42-year-old housewife, who complained of severe epigastric pain and recalled that the symptom suddenly attacked her about 6 hours after eating raw Sebastes inermis. In the gastroendoscopic examination performed about 9 hours after the onset of the symptom, a long whitish nematode larva penetrating the gastric mucosa in the greater curvature of mid-body was found and removed with a biopsy forcep. The nematode was 29. 73 × 0.94 mm in size, had an intestinal cecum reaching over mid-level of the ventriculus and was identified as the 4th stage larva of P. decipiens.
