Let me tell you, folks, we’ve got something incredible here. Meningiomas, they’re big, they’re the second most common tumor in the spine, but what we’re talking about today is something very rare, the clear cell meningioma. Less than 1%, can you believe it? And this case, it’s something else – no dural attachment, that’s unheard of, really special.

We had this young guy, 27, strong, Asian, he’s been through a lot. Seven years ago, he had this brain tumor taken out, then it came back, and we zapped it with radiotherapy. No sign of it since – a real success story. But then, he starts getting this pain in his leg, right? So, we check it out, and there they are, two tumors, clear as day on the MRI, looking like schwannomas, but they’re not. They’re attached to the nerve roots, not the dura, which is just like, wow, that’s not what you expect with meningiomas.

The surgery, it went fantastically. We got everything out, and the guy, he’s doing great, no problems, no nerve issues, and two years later, still no sign of those tumors. And let me tell you, the way these tumors looked, so well-defined, so spherical, it’s like they just popped up on their own, not spread from somewhere else. And they’re different, these clear cell meningiomas, they’ve got this SMARCE1 mutation, not like your regular meningioma.

And here’s the kicker, this is the first time anyone’s reported something like this – multiple clear cell meningiomas in the spine without sticking to the dura, after taking one out of the brain. We think these tumors, they just started on their own, even though it’s been seven years since we dealt with the one in the brain. It’s just, it’s just amazing, really. We’re making history here, folks.
