    Thin rim of non-enhancing irregular calcific wall in the mid-pole.

    The cyst has splayed the mid-pole calyces
    Opposite kidney, ureters and bladder: normal
    No cysts in liver or any other organ

    Hello sir, 

    Incidentally detected asymptomatic renal mass in 52 yr with non enhancing calcified walls, with fairly homogenous hypodense content, would consider primarily an infectious cause, may be aspergillosis which is known to cause such appearance in other organs, though would still keep malignancy ar the back of my mind. Would like to proceed with image guided fnac and proceed depending on its report.
