Prenatal Ultrasound Diagnosis of Meconium Peritonitis Secondary to Cystic Fibrosis

Abstract

This case study describes the ultrasound diagnosis of meconium peritonitis associated with cystic fibrosis. Meconium peritonitis is an intense, inflammatory reaction of the fetal peritoneum due to intrauterine bowel perforation. Because meconium ileus secondary to cystic fibrosis can account for 25% to 40% of meconium peritonitis cases, cystic fibrosis must be a strong consideration. Accurate prenatal ultrasound diagnosis of meconium peritonitis and subsequent testing for cystic fibrosis can aid in establishing an appropriate surgical and therapeutic management plan.
