Abstract: Ovarian tumors are common in clinical gynecology. However, the giant ovarian tumors during pregnancy are not common. Ovarian tumors during pregnancy have little direct effect on the fetus, but various complications and metastatic tumors can pose great threats to the maternal and child health. Common complications include pedicle twist, rupture, infection, and compression symptoms. Compression symptoms also occur when the ovarian tumor grows faster and larger in size, and some ovarian tumors may become cancerous. Combining the 2 cases of pregnant patients with giant ovarian tumors and literature review, we discussed the diagnosis and treatment of this complex disease.
