Idiopathic perforation of normal colon in adults is rare. The cause for idiopathic perforation is not known. We report a case of idiopathic colonic perforation in adult who presented with sign and symptoms of perforative peritonitis. On laparotomy patient was diagnosed to have a colonic perforation. There was no causative factor for perforation in the patient. This case is reported because of rarity of this disease

Worms are rare but definitive cause of intestinal perforation. Ascaris Lumbricoides is the main cause of intestinal perforation, especially in children. Other worms reported to cause perforation include Enterobius vermicularis, Trichuris trichura, and Tania solium. Tapeworm infestation is one of the common problems in tropical countries; usually they are asymptomatic but sometimes associated with serious complication like intestinal obstruction, appendicitis, or perforation. Few cases have been reported of perforation caused by T.solium in the literature, we present here a case report of tapeworm (T. Saginata) causing small bowel perforation and peritonitis.
