Abstract:
Foetus-in-fetu is a rare condition in which a calcified mass is in the abdomen of its host, a newborn or an infant. We report a case of a newborn in whom abdominal radiograph and ultrasonography revealed a mass in which the contents favour a foetus-in-fetu. Diagnosis was confirmed by macroscopic examination that showed a soft tissue mass resembling a foetus, attached to the membranous sac. It was covered entirely with intact skin. There were two malformed lower limbs with a rudimentary digit and one malformed upper limb.
