This is a 23-year-old-woman, primigravida, referred to our unit at 21-22 weeks. The first scan performed at 14-15 weeks was normal. The first scan performed at 14-15 weeks was normal. Her family history was unremarkable in terms of consanguinity and following ultrasound findings were discovered.

Figures 1, 2. 21-22 weeks: unilocular, mid-line, cystic lesion.

  

The cyst was below the stomach, and seen separate from the bladder. A provisional diagnosis of fetal abdominal cyst was made with the differential diagnosis of Ovarian, Mesenteric, Omental, or Duplication cysts. The parents were counseled and a prenatal karyotype with cyst aspiration was given. The possible complications of torsion and pressure effects on the surrounding organs were explained. The importance of follow up with serial scans was emphasized. The parents have refused to undergo any prenatal intervention, but however agreed for serial scans.
