This Teen's Stomach Ache Turned Out to Be Something Horrifying

A doctor in India discovered that a teenage boy had a malformed fetus in his stomach. 

18-year-old Narendra Kumar was complaining of abdominal pains and was taken to Narayan Swaroop Hospital in Uttar Pradesh, a northern province of India. He also suffered weight loss, and bouts of vomiting as reported by Sanjay Pandey for The MailOnline.

An ultrasound and CT scans discovered a 20-centimeter, 2.5-kilogram mass of bone, hair, and teeth in his abdomen.

The mass was reportedly caused by a developmental abnormality called “fetus in fetu.” In this extraordinarily rare condition, one of the fetuses in the early stages of a twin pregnancy envelops the other. The enveloped twin then lives off the nutrients provided by its sibling's blood supply. They’re usually found in the host’s abdomen, although there are reported cases of them being found in skulls and even scrotums, among others.

Speaking to The MailOnline, Dr. Rajeev Singh said:

“Technically, the fetus was alive and was growing due to metabolic activity in his body.”

He added, “In the three-hour-long surgery, we removed a mass of malformed baby, which had hair, teeth, a poorly developed head, a bony structure of chest and spine, with lots of yellowish amniotic-like fluid in the sac.”
