This is the astonishing moment a patient serenaded surgeons with his guitar while he had his brain tumour removed.
Rolden Batista, 40, was handed his instrument in the middle of a complex operation to remove a heart-shaped growth.
And to the relief of the Brazilian surgeons conducting the procedure, he played out a popular local song.
Last year, he was plagued by a series of seizures which alerted to him to something being wrong.
The communications engineer, from Santos, immediately underwent tests at his local hospital.
And X-ray scans revealed that he had a heart-shaped brain.
He told local media: ‘I was told that I had to undergo a surgery and there were two methods.
‘One totally sedated or, two, to wake me up during surgery.’
But because the second option had a much greater chance of success, he decided to choose that. +3

Mr Batista added: ‘The doctor then came up with the idea of making me play guitar in the middle of the operation.’
