Doctors in Mumbai removed world’s largest brain tumor. Doctors at the civic-run Nair Hospital successfully removed the tumor weighing 1.8 kg, from a 31-year-old blind man from Uttar Pradesh.


The surgery was performed on Santlal Pal on February 14 at the Nair hospital in the western city of Mumbai.

The patient, Santlal Pal was admitted to the Department of Neurosurgery with progressive swelling of scalp, headaches, heaviness, and loss of vision in both eyes for the past one year.

The civic body said in a statement, upon examination was detected that he had a firm scalp swelling measuring 30x30x20 cms.

A shopkeeper from Uttar Pradesh said that Mr. Pal’s tumour grew rapidly over the past one year. Doctors said the tumour led to loss of vision, but they hoped he would gradually regain his eyesight.

On February 14, Nadkarni and his team performed a marathon seven-hour-long operation on Pal and the affected skull bone was also removed during the surgery.

Neurosurgeon Dr. Trimurti Nadkarni, said that the tumour was bigger than his own head and after checking all the available medical texts they found that it was the world’s largest tumour.

Dr. Nadkarni said the tumour protruded from the skull and the scalp grew over it. He said, “We had to cut open the scalp and remove the tumour. The part of the tumour within the skull was removed by making an opening in the skull.”

During the surgery, Mr. Pal required 11 units of blood and he was put on ventilation support for three days, according to Dr. Nadkarni.
