Intraperitoneal ascariasis.

Seven children with intraperitoneal ascariasis are reported. One of them had two episodes. There were four instances of free worms in the peritoneal cavity, whereas others had peritoneal abscesses containing round worms. It is suggested that peritoneal ascariasis should be suspected whenever a child presents with peritonitis and/or an inflammatory abdominal mass having evidence of ascarial infestation.
