Did a fir tree grow inside a Russian man's lung after he inhaled a fir tree seed, or was it a hoax?

Link to YouTube video in the vid the surgeon and the patient are interviewed. it was a CNN report

Asking cuz I can't find the actual case report of this anywhere but according to other news reports this case was first published on April 1st 2009. the doctors said the man inhaled a fir tree seed and the fir tree grew in his lung

going to Reddit was unhelpful since they just kept making the same jokes over and over again so I'm wondering if people more knowledgable than me can confirm or deny the authenticity of this lol
