An Indian teenager with chronic stomach pains was shocked to be told they were caused by the malformed foetus of his twin.
Doctors were astonished to find the 2.5kg mass of bone, hair and teeth inside Narendra Kumar’s abdomen.
The parasite had been feeding off Narendra, 18, after forming an umbilical cord-like structure that leached its twin’s blood supply.
He was finally diagnosed with ‘foetus in fetu,’ a rare condition with only 200 cases ever reported worldwide.
The boy’s stomach grew, but his plight went undiscovered for years because neither his parents were of his medical condition nor the doctors could diagnose the condition at an early stage,’ he said.
Dr Singh was the first to perform a proper medical investigation, including an ultrasound and CT scan, before diagnosing the condition.
Doctors then went ahead with surgery to remove the growth, which measured 20 cms in length and had a trunk of hair that was two metres long.
He said: ‘In the three hour-long surgery, we removed a 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.
