Ovarian
tumor in
pregnancy is not rare and benign cystic
teratoma is most common ovarian
tumor in
pregnancy. Most ovarian
tumor in
pregnancy is found at first and
second trimester but sometimes found at
third trimester and it is difficult to make a
decision for management. Moreover
physician should consider
fetal age and
mother's condition, and weigh outcome of operation for complicated ovarian
tumor in
pregnancy. Torsion of ovarian
tumor is not an uncommon complication during
first trimester of
pregnancy and
puerperium but rare occurs during the
third trimester of
pregnancy. We have experienced a case of torsion of benign cystic
teratoma of
ovary which occurred at 37 weeks
gestation in a 25 year-old
woman. So we
report this case with a brief
review of
literature.
