Our examination revealed following findings:

  • Normal fetal growth of the fetus
  • Male fetal gender
  • Two abdominal hypoechoic (cystic) structures with slightly irregular borders – both were localized in mesogastrium, one on the right and the second one on the left side (right one 11,8 x 9,1 mm, left one 8,8 x 7,4 mm)
  • Bowel calcifications were present around the cystic structures

Our presumed diagnosis was double transient abdominal cysts (meconium pseudocysts). Both structures had disappeared later in pregnancy and no anomalies were found at 20 weeks. A normal healthy boy was born at term.

The structural characteristics and typical course of the findings confirmed our presumed diagnosis. Similar, but solitary and huge transient cyst was published here:

I would like to thank Dr. Philippe Jeanty for his input and expert advice regarding this case in November 2020.
