A 56 year-old woman who had eaten raw sardines for dinner the previous evening reported epigastric pain and vomiting. She was treated for acute gastroenteritis, but diagnosed with intussusception of the small intestine when abdominal US and CT showed multiple concentric ring sign the next morning. In emergency surgery, we invaginated the jejunum from 25 cm at the portion about 10 cm distant from Treitz's ligament. After reducing the intussusception manually, we resected about 30 cm of the jejunum due to severe edema. Macroscopically, the resected mucosa was reddish and edematous, but histopathological findings showed the body of Anisakis in the submucosal layer to have eosinophilic leukocyte infiltration. Intussusception is relatively rare in adults, so it is important to note that Anisakidosis may potentially to intussusception of the small intestine.
