Angiomyolipoma: An angiomyolipom is a benign lesion. It does not turn into cancer. The CT appearance is diagnostic. The US appearance of an echogenic lesion is consistent with this. If an angiomyolipoma is very large there is a risk of bleeding, but at a size of 1cm there is nothing to worry about, and there is no need for any treatment. ...Read more

Renal scarring: The upper and lower poles of the kidney or more vulnerable to scarring secondary to reflux. This may have occurred earlier in life secondary to a febrile urinary track infection characteristic for pyelonephritis which during the healing process can lead to scarring. You cannot eliminate scarring once present but you can help to prevent further urinary tract infections specifically with fever. ...Read more

Don't worry!: Angiomyolipomas are never cancer and rarely require treatment. This one renal solid mass that can be diagnosed entirely my imaging studies. If it meets the criteria for an AML you are 100% safe. If the mass become very large and obstructing it could require removal but that is rare. They never turn to cancer. ...Read more

Reasonable: Chances are it is a cyst. It will show on CT and can be characterized better. Also, if that does not give sufficient information an MRI can be considered. The fact that you found it within a year bodes well. ...Read more

You can keep it: even if for a solid mass they usually try to save as much kidney as possible. so for a cystic lesion, it is safer to save more kidney. so unless they are concern about malignancy they usually save the kidney. ...Read more

You may need to seen a Urologist to advice you further ...Read more
