Intussusception in a child infected with enterovirus: case report.
Most intussusceptions in childhood are idiopathic. The association of viral infection has been suspected for decades. We report a case of ileocolonic intussusception in a child during a course of enterovirus infection. A 20-month-old girl with vomiting and irritable crying of 4 days' duration was found to have intussusception by sonography. She had suffered from herpangina one week earlier. Due to her peritoneal signs, she underwent surgical manual reduction. A cluster of enlarged lymph nodes in the intussuscipiens was noted preoperatively by high resolution ultrasound. Two swollen lymph nodes were removed for pathologic evaluation and examined for a viral genome by polymerase chain reaction (PCR) amplification. Panenterovirus base pairs were confirmed on the electrophoresis print. During postoperative sonographic follow-up, significant shrinkage of previous mesenteric lymphoid hyperplasia was observed. In this article, we present the first case of childhood intussusception in associated with enterovirus infection, in which the panenterovirus genome was identified in the patient's mesenteric lymph nodes. This was also the first evaluation of the role of mesenteric lymph nodes in intussusception by high resolution sonography.
