Acute Presentation of Asymptomatic Giant Endometrioma in Pregnancy: A Case Report

Endometriomas are associated with severe endometriosis and are uncommon in asymptomatic women. Reported cases of giant endometriomas are few especially in pregnancy. Decidualization of endometriomas can mimic malignancies in pregnancy. Fetal outcomes can be good after excision of large endometriomas in the 2nd trimester. We present a case of giant endometrioma diagnosed in an asymptomatic woman who developed symptoms after becoming pregnant. Clinical findings, investigations, and histopathology were consistent with ovarian endometrioma. Maternal and fetal outcomes were good after the excision of the mass.
