After 18-year-old Narendra Kumar began experiencing chronic stomach pain and vomiting for no apparent reason, Dr. Rajeev Singh of Swaroop Narayan Hospital in India decided to operate on the teen to discover the cause of his maladies.
Singh discovered a 5.5-pound “mass of malformed baby having hair, teeth, a poorly developed head, a bony structure of chest and spine with lots of yellowish amniotic-like fluid in the sac,” he told the Daily Mail.
The mass was the remains of a twin that became parasitic inside Kumar’s body.
“Technically, the fetus was alive and was growing due to metabolic activity in his body,” Singh said.
As a result of the find, Kumar was diagnosed with fetus in fetu, a condition in which a deformed fetus is found in the body of its twin.
The mass does not have a functional heart, brain, lungs or gastrointestinal tract, according to Mirror.
Fetus in fetu is incredibly rare; there are only 200 recorded cases of it in the world.
The malformed fetus had been a parasitic entity inside Kumar’s body since he was born.
“The boy's stomach grew, but his plight went undiscovered for years because neither [of] his parents were [aware] of his medical condition, nor the doctors could diagnose the condition at an early stage,” Singh said.
Kumar is now recovering, much to the relief of his parents.
“That evil has been tormenting him for years,” Kumar’s father, Prem Chandra, said.
“Now that it has been removed, I am relieved. He can now go back to school and lead a healthy life.”
