Case report

A 34-year-old woman (G3P1) with non-contributive history was sent to our office at 31st week of gestational age due to a cystic structure within the fetal abdomen. 

Our examination found a dominant ovarian cyst of the right ovary (50 x 33 mm) containing a smaller cyst ("daughter cyst sign"). The left ovary also contained a small cyst. The cyst had disappeared spontaneously during the rest of the pregnancy.

Images 1, 2, 3, 4, 5, 6, and 7: The images show a few third trimester scans of the fetal pelvis and abdomen with bilateral ovarian cysts. The bigger one on the right side ("1" on the images 2, 4, and 6) measured 50 x 33 mm and containes a smaller cystic structure (marked by asterisk on the images 2, 4, and 6). The left ovary also containd a small cyst ("2" on the images 2, 4, and 6). The image 7 shows relation of the left ovarian cyst to the left kidney.
