Hello Thanks for query . You have been detected on your CT Scan of abdomen to have Angiomyolipoma of a size of 1 cm in your Rt kidney . Most of the time Angiomyolipoma are usually detected accidentally when Ultrasound Scanning or C.T Scan is done while evaluating other kidney problems . These are benign lesion and if less than size of 2 cm do not require ny active treatment . Since you have single small (1 cm ) Angiomyolipoma you need worry at all . As regards your query regarding time frame about its growth I would state that these are very very slow growing benign lesions and need monitoring every 5 years by doing Scanning . Treatment like Embolization is advised only in a situation when they are large one or cause retroperitoneal haemorrhage . Dr.Patil.
