 Sometimes these endometriosis cases can be overwhelming, especially when you open them up and it looks like a bomb went off in the pelvis. I would just encourage people to go through each compartment step by step. Maybe I'll give you a little bit of history on this one. This is a 35, 40-year-old gentleman who had an ultrasound and they couldn't find the left kidney. And when they scrolled down to the bladder, they saw a mass. So the question is what is your most likely diagnosis? These are your four options. 100% got it correct. The patient does have granulometous prostatitis. The patient had a history of high-grade superficial bladder cancer for which he was treated with BCGI. I didn't give you this history, but you guys didn't need it. I'm going to share with you cases that taught me in one way or another, whether it was in terms of perception and picking up the findings, or it was an aspect of interpretation that was interesting and new.
