Fetus in fetu double trouble: a rare case

Fetus in fetu is a rare condition with incidence of 1 in 500,000 deliveries. Since the condition was first described by Meckel in the late18th century, approximately less than 100 cases have been reported in the literature. We present the findings in a case of FIF that was diagnosed prenatally and we discuss the differential diagnosis between a FIF and a highly differentiated teratoma.
