A 29-year-old female patient, with no history of interest, presented an abdominal mass measuring 25 × 15 cm as an incidental finding during the first-trimester ultrasound in the 17th week of gestation. The lesion, which was dependent on the liver, did not show signs of malignancy on imaging tests (liver ultrasound and MRI); hydatid serology was negative, and tumor marker levels were normal. After multidisciplinary assessment and discussing the therapeutic approach with the patient, we decided to monitor the patient and defer surgical excision of the cyst until after she delivered the baby in order to avoid the risk of miscarriage, while assuming that the cystic lesion had a low risk of causing complications. The patient had a spontaneous vaginal delivery at 41 weeks of gestation. Three months later, the cyst was resected laparoscopically (extraction by minilaparotomy using 2 trocars), including a minimal amount of liver parenchyma. The definitive histological diagnosis was a simple cyst measuring 32 × 24 cm (Fig. 1).
