Fetus in fetu is an extremely rare (1/500,000 live births) congenital anomaly and is defined as a malformed fetus which grows within the body of its twin. It is often overlooked in the differential diagnosis of an abdominal mass in infants or children. Unlike teratomas, fetus in fetu is a benign condition and has no malignant potential. Fetus in fetu is a rare condition with less than 200 cases reported in the world to the best of our knowledge. Although rare, fetus in fetu should be considered in differential diagnosis of paediatric and infantile abdominal masses and in presence of typical Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) findings, appropriate diagnosis can be made. The present article is an effort to review the epidemiology, etiopathogenesis and imaging findings in fetus in fetu.
