Prenatal diagnosis of an inguinoscrotal hernia in a fetus with cystic fibrosis.

detailed anatomic survey of the fetus by an experienced sonographer can detect a multitude of structural anomalies. Although relatively common in the neonate, an inguinoscrotal hernia is a condition that is rarely seen prenatally. In a male fetus, this abnormality typically appears in the third trimester as a complex scrotal mass. Active intestinal peristalsis within an enlarged scrotum is diagnostic of this condition. We report a case that involves the prenatal association between cystic fibrosis and a congenital inguinal scrotal hernia. Serial sonograms from 30 to 37 weeks’ gestation provided the opportunity to follow both the abnormal bowel appearance and the progression of the hernia. Postnatal followup confirmed both diagnoses.
