Fetus in fetu (FIF) is an extremely rare cause of infantile abdominal mass where a rudimentary, malformed monozygotic-diamniotic twin grows inside the other twin. We describe a male infant with double or twin fetuses in fetu. The diagnosis was made on a computerized tomography (CT) scan of the abdomen and confirmed on surgery. Surgical excision was done and the baby did well post operatively.

BACKGROUND Fetus in fetu is a rare congenital anomaly in which malformed fetus grows within the body of its twin. It is almost always detected as an abdominal mass in infancy. It is a parasitic twin of a diamniotic, monozygotic twin. It should be differentiated from teratoma which has no axial arrangement and has got definite malignant potential. Herein, we present a case of a two-month old fem...

Background : Fetus in fetu is a rare congenital anomaly which malformed fetus or parasitic grows within the body of its twin. It twin Diamniotic, monozygotic often overlooked differential diagnosis an abdominal mass infants and children. Teratoma one closest differentials must be excluded. Unlike teratomas, benign disorder. The objective our study to describe sonographic findings extremely path...

Abstract Objectives Fetus-in-fetu is a rare congenital anomaly that occur secondary to abnormal embryogenesis in diamniotic monochorionic pregnancy. Its diagnosis can be accurately made by imaging ultrasonography, radiography, computed tomography, or magnetic resonance imaging. Differential an important issue because FIF, teratoma and cystic meconium peritonitis are very different terms of thei...

Several theories have been given regarding the pathogenesis. One such theory explains the pathogenesis of fetus in fetu as ‘included twin theory’ in which the fetus in fetu represents an aberration of monochorionic diamniotic...
