Surgical Removal of a Gigantic Retroperitoneal Fetus in Fetu: One Case Report

Abstract

AbstractFetus in fetu (FIF) is a rare congenital disorder. At present, the mechanism of FIF has not been fully elucidated. Clinically, the most common site of FIF is the abdominal cavity, while other sites have also been reported, such as from the scrotum to the intracranial space. Surgery is the best treatment for FIF. Our case is a 1-month-old girl. The mother’s ultrasound examination at 36 weeks of gestation revealed that the solid part of the abdominal mass showed strong echoes of the limbs, and the fetus was about 40 mm long. The diagnosis was a parasitic fetus in the fetus. The child was admitted to our hospital for mass resection 1 month after birth, and the tumor was confirmed as a parasitic fetus by postoperative pathology. At present, the patient has had no recurrence after surgery for 5 years. Adequate preoperative evaluation combined with radical surgical resection is an effective strategy for the treatment of parasitic fetuses.
