Increased echogenicity in the lower fetal abdomen: a common normal variant in the second trimester
J. Fakhry, M. Reiser, L. R. Shapiro, A. Schechter, L. P. Pait and A. Glennon
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 suggested by the literature. A possible explanation of this pattern is
offered.
