Then be reassured. When it comes to testicular problems, ultrasound is the ideal scanner. The operator will have seen many previous examples of healthy and unhealthy, er, parts, and you should trust the evaluation. 

Thanks.

I only worry because I've read that 25% of testicular cancer cases are initially misdiagnosed. Although I wonder if they're misdiagnosed before ultrasound, meaning that they never get a chance to have imaging done. Could they make a mistake and misread the ultrasound results? Or miss it somehow? I know it's silly to overthink it but the only thing that will stop me worrying all the time is cold hard facts. Google is a bit hit and miss. 

Thanks for explaining that to me. Because of my reffered medical anxiety I often invent things in my head- and things tend to get out of proportion in my mind. It helps to have someon explain the logic to me. Thanks :)
