Question: Can MRI give correct diagnosis in renal cyst?

 andrea101 - Wed Feb 15, 2006 9:19 am

My husband is 67 years old and gets annual CT scans as follow up due to a melanoma removed from his chest 4 years ago. A year ago abd ct showed several small renals cyts. This year one showed up as high denisty renal lesion and was followed up with an MRI w/wo contrast. The report is as follows:
-there is an exophotic lesion from mid right kidney measuring 2.5cm; on T1 it is hyperintense in signal, also on T2. Therefore this is most likely a proteinaceous cyst or homorrhagic cyst. There is a cyst seen in the upper pole of the right kidney measuring 1.5 cm..

Can an MRI adequately determine the difference between a hemorrhagic cyst and a renal cell carcinoma? Would not a follow up with a nephrologist be appropriate to obtain more informationre these cysts?

thanks for your help...andrea

User avatar Hi andrea101,
Generally speaking, there are certain characteristics that that are distinguishing between a benign and malignant mass. A physician (Radiologist) typically will state on the report, for example, "appears to be a benign nature" or "suspicious for malignancy/malignancy can not be excluded" in which case if the statement would be the latter, there would also be a statement "Abnormality Attention Needed" and follow up recommended.
