Doctors care for a baby male child in Mumbra , India , were shock to discover he was " pregnant " with his own matching crony .
During a routine CAT scan of his female parent during maternity , radiologist Dr. Bhavna Thorat spotted an abnormal mass on the baby . When the baby was bear , Dr Thorat performed a scan of the newborn .
The scan revealed a 7 - centimeter growth inside the baby ’s abdomen , thought to be the baby ’s twin , which had been enveloped in the womb .

The growth appeared to be a example of " fetus in fetu " , an extremely rarefied abnormality where a fetus becomes enwrap by its own twin . After identifying the hoi polloi , surgeons successfully operated on the newborn infant , removing the 7 - centimeter - long foetus from his abdomen .
The baby and his mother were move to Titan Hospital in Thane after OR , where they are both recovering well .
Less than 100 cases of " fetus in fetu " have ever been recorded worldwide , with the abnormality materialise in onlyone per 500,000 births .

One theory on how it happens suggests that the " parasite " twin begins as a normal fetus , share a placenta with its sibling . Early during pregnancy , however , the horde twin envelopes the other twin . The Gemini that has been enveloped becomes a " sponger " as it uses the emcee Twin Falls ’s blood supply to survive .
In cases of foetus in fetu , the " parasite " twin lacks the pipe organ it needs to survive outside of the twin andthreatens the spirit of the host it inhabit , as both twins attempt to get the nutrition they ask from a single umbilical electric cord .
commonly , the twin has no brain or life-sustaining Hammond organ , however in this character the doctor report check a brain within the parasitic fetus .

" It was inside a foetal sac of the newborn , " Dr Thorat , who took the initial scans , said to theDaily Mail . " I could see finger cymbals of the upper and lower limbs of the fetus . "
" The unique thing about it was I could see a bantam head with the brain inside , " Thorat added . " However , this parasitic twin did n’t have a skull bone . "
With the mint off , the surviving twin is doing well and no problems have been cover .
