I have an enlarged spleen. A bone marrow biopsy came out fine. I have recently had a diviticulitus attack treated with antibiotics and broke two ribs a few weeks later. They discovered the enlarged spleen doing CT scans for the diviticulitus, confirmed it with a pet scan. Is there a possible cause effect relationship here? My hematologist wants me back in five months to see if the spleen has gone down in size and for follow up blood work. My internist says I am in a transitional state. I m not sure what he means by that.
