Lumbar spine MRI found T2 bright focus within interior Rt hepatic lobe measuring 2 cm & superior medial Rt kidney measuring 2.1 cm? What could it be?

Here are some... Glad and congratulate for getting good healthcare including deepening into MRI study. For your best possible practical benefit, you should refer this question to the doc ordering this test since he/she should know more about your medical profile than anyone online. Further online chat for such may incur unnecessary confusion, anxiety, & fear due to lacking enough space to elaborate. Best wish...
