A three-year-old toddler in India, Roona Begum, whose head swelled to three times its natural size is undergoing a dramatic resurgence.

Surgeons in New Delhi carried out a series of operations to reduce the size of Roona’s head from 37in to 23in but she was later discharged with little chance of survival.

However, in a miracle transformation, the surgeons were amazed to find that not only is Roona alive – but is well enough to even smile.

She is able to crawl, eat and interact with her loving parents, but is unable to walk because of the weight of her head.

Roona’s mother Fatima Khatun has said that she hopes her daughter will one day go to school.

The toddler was rushed to hospital in New Delhi, India, last year, suffering an extreme form of hydrocephalus – water on the brain.

She was admitted to the Fortis Memorial Research Institute and Hospital in Gurgaon, on the outskirts of New Delhi.

Her treatment was reportedly done for free in the hospital after Roona’s plight attracted international sympathy.

The surgeons are keen to proceed with yet another operation to further reduce the size of her head to normal size.
