This was a 30 year old lady referred for 2nd opinion for fetal lower abdominal mass.
There was no history of any consanguinity.
The lower abdomen showed a predominantly cystic mass with septations and internal echoes .
This was distinct from the urinary bladder and the kidneys. Both the kidneys showed mild pelviectasis.

Several possibilities come to mind in the differential, the whole spectrum of what could be expected in a female fetus, including hemmorhagic cyst as mentioned, dermoid, mesenteric cyst, peritoneal cyst.

Mesenteric cyst is a DD.

I wouldn’t think it’s a dermoid without seeing any calcifications right away. I don’t see any pictures with color flow to show if there was flow with the septation or ? tissues. By any chance, did you optain any?
