Introduction: Fetus-in-fetu is a rare congenital fetiform mass whose etiology is still controversial. We report two cases of fetus-in-fetu. Case 1: A fetal retroperitoneal cystic tumor including two masses was detected by ultrasonography at 26 gestational weeks. The masses showed distinctive structures resembling a vertebral axis and were prenatally diagnosed as fetus-in-fetu. A resected specimen revealed two fetiform masses. Case 2: An intracranial tumor with hydrocephalus was detected by… Expand

TLDR
A case of a newborn in whom abdominal radiograph and ultrasonography revealed a mass in which the contents favour a foetus-in-fetu, attached to the membranous sac. Expand

TLDR
A further case where borderline pathological features are present is described to discuss and compare briefly the retroperitoneal teratoma and foetus in foetu, emphasizing that the former is a true tumour while the latter is not. Expand

TLDR
It is demonstrated that fetus in fetu can be diagnosed prenatally if the fetiform mass has well-developed limbs and spine if a well-defined encapsulated cystic mass with calcified solid components is detected prenatALLY in a fetus by ultrasonography. Expand
