Kyle Sandilands: Radio shock jock reveals grim brain aneurysm update on Building The Show episode
The radio shock jock has revealed a worrying development in his ongoing health battle with a brain aneurysm.
Kyle Sandilands has revealed his brain aneurysm has grown in a “terrifying” update shared on his Building The Show series.
The shock jock, 55, documented a recent medical appointment for the new show months after previously delaying further treatment for the health condition.
Sandilands was diagnosed with a brain aneurysm in February 2025 after experiencing persistent headaches. At the time, doctors determined that surgery carried significant risks, including the possibility of stroke.

In a teaser video for the episode titled ‘The Appointment’, Sandilands described the agonising wait for his results.
“I just really hate the whole doctor environment. Sitting in that waiting room with all the other people waiting for a death sentence as well,” he said.
“It’s not like a GP, everyone that is in there has got some sort of chronic, serious problem, and the vibe is just negative in there.
“Everyone is in there wondering ‘oh and I going to be told today is the day I die? Or is today the day I need the operation?’ It’s really daunting.”
After receiving the results at the specialist appointment, Sandilands told his viewers the aneurysm had grown by one millimetre.
“It’s grown a little bit, which is great news. So I come out of the doctor’s office, and unfortunately the aneurysm has gotten bigger,” Sandilands said in the episode, as cited by Nine.
“One millimetre bigger, which seems small, but I didn’t want to get that.”
Sandilands described the results as “not a good sign,” and added that the grim outlook “terrified” him.
“That was the last thing I wanted to hear. I was hoping, and in my mind I thought, oh, I’ve got this. I’m going to make it smaller,” he added.
“But it was bigger. Not big enough yet for them to operate. Not a good sign moving forward.
“A life of bad choices has probably led me here.
“I’m full of regret. I do not want to die, and I do not want to be carved up.”
According to Health Direct, a brain aneurysm occurs when a weak area in the artery wall causes a blood vessel in the brain to bulge or balloon.
The condition can become life-threatening if the aneurysm bursts and causes bleeding in the brain.
