A CASE OF INTUSSUSCEPTION CAUSED BY INFANTILE INTESTINAL DUPLICATION

Abstract

A nine-month-old male infant was taken to the hospital because of vomiting and sullenness. He was delivered normally. A mass was palpable at the right side of the abdomen and an ultrasonography (US) revealed target sign and a cystic mass. Then he was admitted with a suspicion of intussusception. Gastrographin enema revealed a filling defect characteristic of intussusception in the colon, which could not be reduced. Abdominal computed tomography (CT) showed multiple concentric ring and the cystic mass in the ascending colon. An emergency operation was carreid out with a diagnosis of intussusception caused by duplication of th intestine or the mesenteric cyst. The intussusception had been reduced. The mass was identified in the terminal ileum. It could not be resected by itself, and required an ileocecal resection. The mass was round in shape and identified near the terminal ileum on the mesenteric side. Histopathologically the tumor had common muscular wall and its own mucosal lining. So duplication cyst was diagnosed. It is difficult to diagnose the duplication preoperativery due to its atypical type of location, size, form, age, and symptoms. In case in which nonoperative reduction leads to failure in the child intussusception, it is necessary to explore the leading point carefully with the radiographic appear-ance.
