Hemangioma in my case. I had an MRI but in the end it was a surgeon with the right experience looking at an earlier ultrasound that diagnosed it.
I had trouble believing he'd diagnosed it when he glanced at the ultrasound and calmly said what it was. Given I'd had medical practitioners send me for neurological studies to check it wasn't all in my head, suggest fusing my wrist to stop the pain, tell me there was nothing visible in X-ray, MRI, or the same ultrasound report the surgeon diagnosed me from... It seemed unlikely anyone could do an apparently simple diagnosis like that.
