Can a Dromedary hump be isoechoic or hypoechoic?

User Profile
I have some questions regarding an US showing an isoechoic lesion in my left kidney. Since I posted my previous question, I\'ve learned here that isoechoic lesions are common in case of tumors (benign or malignant), angiomyolipomas and complex renal cysts. But I also found in the Internet certain condition called "dromedary hump kidney" (described as a pseudotumor), which is not rare in left adult kidneys, but sometimes it\'s said to be isoechoic or mostly hypoechoic (depending on the source). After looking at some US images of that condition and comparing them to my US results, I find them to be very similar, but of course I\'m not a radiologist or doctor, and my doctor didn\'t want to say what kind of lesion I have, until more studies are done. So I\'m still getting a contrasted CT and all necessary studies, as mine could be a life threatening condition. But my doubts are: can a dromedary hump be isoechoic or it is always hypoechoic? Does a dromedary hump appear when one gets old?

Dromedary hump is not a actual tumor. Dromedary hump is a radiological description of the lateral aspect of the left kidney, due to the impression of the spleen. The appearance can be misinterpreted occasionally as a tumor originating from the kidney, and hence the Dromedary hump is described as a pseudotumor appearance.

But since the tissue is normal renal cortex, it has a isoechoic nature, as seen on the ultrasound. And since this hump is developed due to constant modelling of the kidney around the spleen, it is seen predominantly as one grows older.
