An insulinoma is a rare tumor that originates in the β cells of the pancreas with an incidence of four cases per million people per year. To our knowledge, 40 cases of insulinoma in pregnancy have been reported. Insulinoma in pregnancy is usually diagnosed in the first trimester. Surgical treatment is advised during the second trimester with complications arising in up to 10% of cases. We present the case of a 34-year-old pregnant woman diagnosed with insulinoma during the first trimester. The patient underwent a laparoscopic resection of the tumor at 15.5 weeks of gestation. Insulinoma was resected and postoperative complications were managed, including acute pancreatitis and peripancreatic and splenorenal fluid collection, which were treated using multidisciplinary management and resolved at the end of the pregnancy at 40.1 weeks of gestation.
