Multidetector computerized tomography in diagnosis and preoperative workup of fetus in fetu: A case series

Fetus in fetu is a rare disorder with a reported incidence of 1 in 500,000 live births, with only 78 cases reported so far. The most common presentation is abdominal mass in a newborn or infant; however, presentation in later life is also possible. Early detection is by ultrasonography. Computerized tomography is rarely used. However, computerized tomography gives an excellent overview of anatomical information and its exact relation with the surrounding viscera. The present case series is an attempt to highlight the role of cross-sectional imaging in the pre- and post-operative management of this rare disorder.
