A provisional diagnosis of fetal abdominal cyst was made with the differential diagnosis of Ovarian, Mesenteric, Omental, or Duplication cysts.

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.
