Intussusception due to intestinal anisakiasis: a case report.

This report describes our experience of intussusception due to intestinal anisakiasis which was treated by laparoscopy-assisted surgery. The unique sonographic findings of this complication were a pseudokidney sign and a target sign with an edema of Kerckring's folds in the intussusceptum. Surgeons should know about intussusception as a rare complication of intestinal anisakiasis. Sonography, computed tomography and laparoscopy are helpful in diagnosing and treating this complication.
