A gestational corpus luteum cyst is the most common adnexal mass in early pregnancy and rarely exceeds five cm in diameter. Thus, surgery is rarely indicated. The present study reports the case of a 24-year-old pregnant woman who presented with a large adnexal mass that manifested as a large corpus luteum cyst at 32 weeks of pregnancy which required surgical intervention due to significant abdominal discomfort reported by the patient.
