What's your diagnosis of this lesion in a woman who is 34 weeks pregnant?

5. Huge maternal ovarian cyst with pregnancy

The cystic lesion shows thin walls, ruling out septate uterus. These findings confirm a cyst on the maternal right ovary, possibly serous cystadenoma. This was a known case of right ovarian cyst.
