Hi, Thanks for writing in. There can be many spots that can be seen in kidneys, ovary and appendix. Most of them are from benign causes and only some have a malignant cause. Without knowing the details of the spots with respect to size, appearance and location, it is difficult to confirm the health concern. This is the reason you had to get another scan done with contrast dye injected through intravenous route and this will help delineate the characteristic features of the spots under evaluation. It will be better if you can include details of your symptoms and its duration. Findings of ultrasound scan and CT scan are also important when discussing the probable conditions. Please also include a noted on the cancer type prevalent in your family. Please do not worry.
