Ascarid granuloma presenting as pseudotumour.

Three patients with histologically confirmed ascarid granuloma who presented clinically with abdominal masses simulating abdominal tuberculosis or lymphoma are described. The clinical course of one patient was complicated by the formation of a spontaneous faecal fistula and perforation of the terminal ileum. In two cases there was rupture of the inflammatory pseudotumour through the anterior abdominal wall.
