Mirela Gradinaru, 37, arrived at the clinic in Arad, western Romania, in agony, begging docs to help.
But she refused to tell surgeons how the can came to be lodged in her butt even after a successful operation dislodged the canister.
"This was not just a little can of deodorant, this was a massive can of hair spray."
Mirandolina Prisca, a doctor at the clinic, explained: "We had X-rays done to localise the object and then we carried out the operation. The patient was fine after it.
"She was very embarrassed. She was clearly in a lot of pain, however it got there."
"This was not just a little can of deodorant, this was a massive can of hair spray," said one hospital worker.
It wasn't a surprise the docs never got to the bottom of this medical mystery!
We all KNOW how it got there! Naughty, naughty!
