The 18-month-old baby, who is suffering from a rare medical condition - Hydrocephalus, was admitted to Fortis Memorial Research Institute (FMRI) in Delhi on Tuesday night for treatment.
Help began pouring in for Roona Begum's family after reports of her suffering from Hydrocephalus reached all over the world.
Neurosurgeon Sandeep Vaishya told Agence France-Presse that Fortis would fly the girl down from her home to the hospital. He said that the hospital charity would fund the medical expenses.
Roona's father Abdul Rehman, who works in a brick factory and earns about ₹150 per day, said that they don't have enough money to pay for her treatment. The surgery for hydrocephalus is very expensive; basic cases cost around ₹1.25 lakh.
Roona Begum is suffering from Hydrocephalus or "water on the brain" that causes her head to swell like a balloon. Due to the condition, Roona's head has swollen to more than double its normal size to a circumference of 91 centimetres (36 inches).
"This is a congenital condition where the overgrowth starts in the womb. I have seen hundreds of such cases but this is an exception. Perhaps, this is the biggest in the world," Sandeep said, according to Hindustan Times.
"The flow of the fluid can be diverted through a surgery but we need to examine her first. Her condition is too severe. She is underweight and also her bones are still not fully grown."
Rehman told the My Good Act organisation that 10 to 12 doctors have observed her till Wednesday and different types of scanning of her head have been conducted.
Hydrocephalus is a medical condition that causes abnormal accumulation of cerebrospinal fluid in the brain's cavities causing it to swell like a balloon.
It is often treated by implanting a shunt, soft and pliable piece of tubing, into the affected region through a small hole made in the skull and letting the excess liquid drain elsewhere in the body.
