In that case, ultrasound can detect subtle deferences in texture, there are some benign things that can mimic a mass in a kidney. Among then are: Column of Bertin ( an extension of the renal cortex in between the renal pyramids) , a duplex kidney ( one that is sort of like two kidneys that didn't actually divide), Angiomyolipoma ( a fatty mass) and even an irregular contour can appear mass like. Sounds like it's just something to be watched, maybe rescanned with both modalities.The good news is that it was not an obviously suspicious mass on the CT!

So, the answer, is unfortunately . .yes a CT can miss a solid mass . . the mass can sometimes be positioned or hidden behind structures in the body, or misread . . you might consider requesting a second CT in a few weeks or months in order for the scans to be compared and see if there is any difference.
