So I've been getting all kinds of diagnostic imaging tests of my left kidney, because they spotted a mass late last year. After my MRI on Thursday, they found the culprit. I have two left kidneys! How funny is that?
My parents used to tell me that I was born with a hole in my kidney, but I never asked any other questions and have never had any kidney function problems or issues. It's a rare occurrence, but a benign condition. Nice to have a spare, though.
