Abstract: The adnexal masses during pregnancy include physiological cysts， inflammatory masses， benign neoplasms and malignant neoplasms， and its incidence has been increasing in recent years. Physiological cysts usually spontaneously resolve in the middle or late stage of pregnancy or after delivery. Benign ovarian neoplasms without complications or obstruction of the birth canal can be closely observed during pregnancy，while malignant ovarian neoplasms which endanger the safety of both mothers and fetuses require active intervention. Therefore， it is of great significance to make diagnosis and differential diagnosis of ovarian malignant neoplasms in pregnancy. During the diagnostic process， the results of imaging tests and tumor markers need to take pregnancy into consideration. This article mainly describes the diagnostic methods and characteristics of adnexal mass during pregnancy.
