Fetus in fetu – a rare developmental anomaly

Abstract

Fetus in fetu is a rare condition which most often presents as a fetiform calcified mass in the abdomen of its host, fetus or newborn. We report a case of 8-month-old girl with history of abdominal distension. Ultrasonography and computed tomography scan revealed a mass in which the contents favor a fetus in fetu rather than a teratoma. She underwent surgery and the mass was resected in toto. Radiograph of the resected specimen showed the presence of rudimentary vertebral column which was later confirmed by pathologist. Keywords: Fetus in fetu (FIF)
