title: Ultrasound diagnosis of fetal annular pancreas.
abstract: A case of fetal "duodenal" obstruction was brought to our attention at 37 weeks gestation. The patient was referred to our Prenatal Diagnosis Center with an ultrasound finding of "double bubble" in the abdominal area of the fetus. We submitted the patient to an aimed ultrasound examination in order to establish the etiopathogenetic mechanism and to perfect the diagnosis. The ultrasound scans of the epigastric region strongly suggested the presence of annular pancreas. The diagnosis of duodenal stenosis due to annular pancreas was confirmed at birth and the infant underwent corrective surgery: duodeno-jejunostomy was successfully performed. We would like, in this context, to stress again the powerful diagnostic value of ultrasound investigation, when dealing with complex fetal malformations. The present report shows that high resolution echographic equipment and the ever-increasing qualification of medical staff make it possible to envisage the presence of annular pancreas already in prenatal life.
