Re: fatty lesion on kidney
I had a CT scan and I have one on top of my right kidney. Here is what I found out about them. I am not sure if yours is the same as mine?
Also known as renal hamartoma, angiomyolipomas are rare benign tumors usually caused by an inherited genetic mutation. They can occur on an isolated, individual basis, but most often are associated with a rare genetic disease called tuberous sclerosis, which can cause tumors in the skin, kidneys, brain, and other organ systems. About 80% of persons diagnosed with tuberous sclerosis also have angiomyolipoma.
In patients without tuberous sclerosis, these tumors most often occur in middle-aged women. Most cases are discovered when the patient undergoes a CT scan for an unrelated abdominal problem, suffers gastrointestinal discomfort, or suffers a sudden hemorrhage caused by the rupture of a large tumor.
Management of the condition depends on the size of the tumors and the severity of the symptoms they produce. Asymptomatic patients and those with small tumors usually are not treated; instead, they are observed periodically with an eye toward surgery if the tumors grow or produce symptoms. Because of the potential for spontaneous rupture and life-threatening hemorrhage, patients with large tumors usually are considered candidates for some form of surgical treatment, ranging from partial nephrectomy to arterial embolization.
