Meckel's diverticulum, the remnant of the vitelline duct, is the most frequent congenital anomaly of the small intestine. It rarely adheres to the ileal mesentery with the vestige of the embryonic vitelline artery called the mesodiverticular band, and this bundle may cause strangulated ileus. We examined a 4 1/2 year old male with abdominal pain, nausea, and vomiting by ultrasound before performing an emergency operation. Color Doppler flow mapping helps to preoperatively diagnoses the strangulated ileus due to the mesodieverticular band. This report describes the ultrasound findings and a review of relevant reference material.
