question: Hello Doctor, My dad is suffering pain down to his chest in the left side. and previously we thought may be it is related to heart then we underwent a 2d echo but the report came as normal. then we went to an orthopedic Dr. and he suggested us to go with Ultrasound for abdomen. and it was found that it has got cortical cyst measuring 49 X 35 mm in right kidney . Pls suggest what can be done. Thank u
