Ovarian masses are not uncommon in pregnancy. Incidence of ovarian mass in pregnancy is reported to be about 1 in 1000. The most common ovarian masses seen in pregnancy are functional cysts of ovary; others being benign cystic teratomas, serous cystadenoma,paraovarian cyst, mucinous cystadenoma and endometrioma. The major concern of ovarian mass in pregnancy is it’s likely complication to undergo torsion (partial or complete twisting of ovary on its ligamentous supports, often resulting in impedence of its lymphatic and venous outflow and arterial inflow leading to stasis,venous congestion, haemorrhage, necrosis and sometimes cyst rupture). Predisposing factors associated with torsion are moderate to large size of ovarian mass, long pedicle and free mobility. Here we are presenting a case report of a huge ovarian mass detected and managed in early pregnancy.
