ABSTRACT

The giant forms of ovarian cystic teratoma are not common and even rare in pregnancy. Case presentation: A 29 year old multipara who presented to our facility with recurrent abdominal pain of 2 years, abdominal swelling of 20 months duration and pregnancy of 18 weeks gestational age.

She was managed for twisted ovarian cyst in pregnancy and subsequently had laparotomy and right salpingoophrectomy. Histology revealed mature cystic teratoma of the ovary.
