Prenatal Sonographic Detection of Meckel Diverticulum in Utero with Postnatal Radiologic and Surgical Confirmation

Meckel diverticulum is the most frequent congenital malformation of the gastrointestinal tract, occurring in approximately 2% of the population. Diagnosis of Meckel diverticulum in the pediatric population is made most often by a nuclear medicine scan and also by fluoroscopy, plain-film radiography, computed tomography, and magnetic resonance imaging. We present a case of Meckel diverticulum evident in utero on a prenatal sonographic examination performed at 33 weeks' gestational age. There were no prenatal complications, and postnatal surgery confirmed Meckel diverticulum. In view of the rarity of Meckel diverticulum, we hope this information will aid radiologists involved in fetal sonography to help determine the differential diagnosis of anechoic intraabdominal masses in the fetus.
