I had a splenectomy in 2004. In 2009 I had an US on the abdomen for hematuria. The US report stated the spleen appeared normal. I have heard that if any splenic tissue is left, that the spleen can regrow. Is it possible that my spleen had grown back (great for my immune system!) or is there other abdominal tissues that could be misread as a spleen? When I received the report, I questioned the clinic staff. They brought it to the radiologist's attention but he only had them delete the comment about the spleen and did not reread my test. Is it worth my time and money to have another US? Not having a spleen has complicated my being able to have other procedures because the treating doctor is concerned about the compromised immunity/risks for infection. Thank you for your assistance.
