The fetus in fetus (FIF) is a rare congenital pathology with less than 200 cases reported in the literature worldwide, in which a pregnancy with monozygotic twins one of them develops normally, while the other atrophies and it is inside the developed twin. The most frequent location is retroperitoneal; however, multiple cases have been described in the sacrum, mediastinum, skull and neck. We present a case of a 17-dayold female patient diagnosed with a congenital abdominal mass. After the extraction, an anatomopathological analysis was performed. There were multiple limbs, vertebral column, anencephalic cranial cavity, and the diagnosis of FIF was concluded.
