After having a ct scan and biopsy on Oct. 18, my report says that I have a left retroperitoneal mass with soft tissue and fat densities raising the question of adrenal myolipoma or renal angiomyelolipoma. I tried to look up definitions of these conditions on line but have not found anything about them. I will try to make an appointment with the doctor who performed this biopsy, but in the meantime, I would appreciate any further information on my condition that you could provide. Thank you.
