A baby
was born in Armenia with a parasitic twin fetus, a local Haykakan Zhamanak
Daily writes.
The parents applied to specialists after the belly of
their newborn girl began to grow. Head of the Arbakir Medial Center Ara
Babolyan says a parasitic twin fetus was found inside the girl's belly. The
baby underwent surgery and the fetus was successfully removed. It is a very
rare phenomenon.
Fetus in fetu is a developmental abnormality in which
a mass of tissue resembling a fetus forms inside the body. There are two
theories of origin concerning "fetus in fetu". One theory is that the
mass begins as a normal fetus but becomes enveloped inside its twin. The other theory is that the mass is a
highly developed teratoma. "Fetus
in fetu" is estimated to occur in 1 in 500,000 live births.
