Hello, The report you have mentioned in the question is an ultrasound report. It is not an x-ray. The ultrasound points toward the possibility of an angiomyolipoma. It is a benign tumor of kidney. It can occur without any other associations. It can also occur in people with a syndrome known as tuberous sclerosis. This tumor as the name implies have angio blood vessels, myo muscles, and lipomatous fatty components. It arises from the cells surrounding blood vessels. The tumor does not cause much harm usually. Rarely it will invade blood vessels and cause bleeding. Very rarely the tumor can have association with clear cell type of renal carcinoma. Some people can have similar lesions in lung and kidney. My advice to you is to consult a surgeon. The mass can be either embolized or excised depending on size. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Meera Rajeev
