I have a 8 cm hematoma on my liver. (I ended up in ER with severe pain - thought I was having a heart attack). Several CT's and an MRI are NOT showing any adenomas or hemangiomas as a cause for this hematoma. I did NOT have any trauma to my liver. The doctor is stating that he does not know the cause of the hematoma - I have a CA125 of 150. No masses found anywhere else. His course of treatment is to play the waiting game - come back in 4 weeks and do another CT and blood work and we'll check to see if it is shrinking and if the CA125 levels go down. I am very uncomfortable with not knowing the cause of this. Has anyone heard of this before?
