Abstract
Hyperreactio luteinalis is a rare, benign ovarian finding during pregnancy, but its sonographic appearance can imitate a malignant process, and the ovarian enlargement predisposes a woman carrying this anomaly to other complications. The management of hyperreactio luteinalis during pregnancy is preferably conservative, and surgical treatment is reserved for the cases with associated complications. This article reviews maternal ovarian hyperreactio luteinalis in pregnancy and demonstrates an example. Proper assessment of the maternal hyperreactio luteinalis helps to prevent its unnecessary surgical treatment.
