Yes, I was diagnosed with one in 2019. Unfortunately, the discovery came too late to spare the damage to my optic nerve and vision. It had grown wrapped around my optic nerve sheath, so the doctors wouldn’t even biopsy it, much less perform surgery to remove it. I ended up undergoing 28 daily radiation treatments to kill the tumor. It did not restore my vision, but it is not currently growing. For reference, I was 55 when diagnosed.
