Thanks so much for the reply. No liver concern but his bloods did come back with low platelets, which I think corresponds with the enlarged spleen. He's had no GI bleeding.
There is so much info from the CAT scan that we just weren't expecting. I had never heard of a 'filling defect' before...does this mean it's not a tumor? Sorry if this is a stupid question. I'm going to do some research on portal hypertension.
Quite a bit going on there and it's good his doctors are engaged. What maybe a clue here is his enlarged spleen. This quite often indicates portal hypertension which is the GI portal blood flowing to the liver. When the portal blood flow is disrupted, the flow resistance causes the increase in the portal blood pressure and leads to an enlarged spleen, esophageal varices, GI bleeding, etc. Has he been having any liver concerns as well?
