In a rare occurrence, a woman delivered twin baby boys, joined at the head, in a hospital in Tonk, about 90 km from here, on early Wednesday morning.

The twins, born to Arsi (24), are Dicephalic Parapagus, meaning they have separate heads but are joined from the neck down.

According to doctors, such an occurrence is extremely rare, with this being only the third known case in India and the first ever in Rajasthan.

The twins have a single heart, a single stomach with two food pipes, and two nervous systems.

Doctors at the city’s J.K. Lone paediatric hospital, where the twins were brought on Wednesday, say the twins are inoperable. However, they have not ruled out the chances of them surviving.

“They are inoperable and cannot be operated upon anywhere in the world,” S.D. Harma, Superintendent, J.K. Lone hospital, told The Hindu.

“We have constituted an expert team and they are examining the twins under my supervision to find out the possible course of treatment,” said Dr. Sharma.
