Fetus inside: Baby born with rare medical condition in K'taka

The child is suffering from a rare congenital condition called ‘Fetus in Fetu’ (FIFS). As defined by the U.S. National Library of Medicine (NIH), fetus in fetu is an anomaly where a malformed fetus grows inside the body of its twin. It is considered a parasitic twin, distinct from a teratoma — a tumour-like growth with malignant potential that lacks organized development.
