Doctors at Buldhana District Women’s Hospital, Maharashtra, detected a rare “foetus in fetu” case, where an underdeveloped twin is enwrapped inside the body of the other in a monozygotic twin pregnancy.
This rare congenital disorder, affecting about 1 in 500,000 births, results from an uneven embryo split, leaving one twin trapped within the other.
The parasitic twin, dependent on the host twin for nutrients, has some fetal features but cannot survive independently.
In this case, it was detected during a routine scan, and doctors successfully removed it after a C-section delivery.
