Echogenic fetal bowel in the third trimester associated with meconium ileus secondary to cystic fibrosis. A case report.

Abstract

Echogenicity of the fetal bowel seen sonographically can vary at different gestational ages. Increased echogenicity of small bowel loops is seen commonly in the second trimester. We encountered a case of increased bowel echogenicity with shadowing in the third trimester in a fetus who had meconium ileus associated with cystic fibrosis. Other reports also indicate that a persistent echogenic appearance of fetal small bowel in the third trimester, particularly with shadowing, is worrisome and can be associated with meconium ileus.
