Case report
A 46-year-old woman, (G1P0) without unremarkable obstetrical history.
Our ultrasound examinations in the first and second trimester were normal.
At 34 weeks of gestational age an ultrasound scan revealed a left anechoic irregular image located in the pelvis, suggestive of ovarian cyst (images 1-4).
We were not sure about the diagnosis because of the irregular structure of the cyst.
Both kidneys were normal and the cyst was close to the bladder.
At 36 and 38 weeks of pregnancy, we saw changes inside the cyst suggestive of hemorrhage (images 5-8) without ascites (image 9).
The fetus moved normally, and middle cerebral artery velocity was normal.
A female baby was born at 38 weeks and surgery was done 3 days later. The left ovary was necrotic and it was removed (image 10). The right ovary and the uterus were normal. The final diagnosis was a classic ovarian cyst (cystadenoma).
Images 1-4: 2D ultrasound scan images revealed left ovarian cyst.
