Increased echogenicity in the lower fetal abdomen: a common normal variant in the second trimester.

Abstract: Ten cases displaying a focal area of increased echogenicity in the lower fetal abdomen on prenatal sonography are reported. This was an isolated finding in each case. Nine cases were noted early in the second trimester. The last case corresponded to a postmature gestation. In all cases, a normal lower abdomen was documented on follow-up prenatal sonography, at birth, or at autopsy. The authors believe that increased echogenicity in the lower fetal abdomen represents a normal variant that is more common than su… Show more

“…Fetal meconium production does not begin until the second tri mester and may be a cause for the appearance of hyperechoic fetal bowel at this stage in fetal development [6]. In normal fetuses, the hyper echoic image of the fetal bowel usually disap pers by 20 weeks on serial sonograms [1][2][3]. In the present series, echogenic fetal bowel ap pears to be consistent with a normal neonatal outcome in the majority of cases.…”

“…No clinical evidence of bowel pa thology was found in this neonate. Fakhry et al [2] also reported a normal outcome for a case of fetal echogenic bowel discovered in the third trimester which persisted until term. Due to the small numbers of cases reported in the literature and the lack of follow-up throughout pregnancy, it is unclear what pro portion of fetuses in a low-risk population with persistence of echogenic bowel into the third trimester have an ultimate diagnosis of meconium ileus and cystic fibrosis.…”

“…Denholm et al [2] first reported a relation to cystic fibrosis (CF) in 1984. Once considered a normal variant, FEB has since been linked to many diseases including CF, aneuploidy, congenital infection, fetal abnormalities, gastrointestinal obstruction or perforation, intra-amniotic bleeding, in utero growth retardation (IUGR), intrauterine fetal death (IUFD) and fetal alcohol syndrome [3][4][5][6]. The purpose of this study was to analyze diagnostic findings in FEB and the corresponding outcome of pregnancy in order to identify indicators of high-risk situations.…”
