[|Human|] Hi, I have been suffering pain in my right side for the past few months together with a feeling of nausea and have had a few episodes of vomiting bile and severe pain in my side. I have had an ultrascan, a CT liver scan and am awaiting an MRI scan . My doctor has said that they have found 4 leasons on my liver and they need to investigate this further - can you tell me what the likely cause of this is please?
[|AI|]  Hi, Thanks for writing in. A double contrast CT of the abdomen will reveal whether the lesions are solid or cystic, vascular or avascular. This will lead to a clue whether they are benign or malignant in origin. If still the surgeon is unable to comment then a CT guided FNAC of the lesion will help in arriving at a diagnosis. MRI scanning is not so helpful in diagnosis of abdominal lesions. Since you have nausea or vomiting then there is a likelihood of the primary cause being in the upper GI tract. This can be investigated by upper GI endoscopy. I hope this answers your quarry. Regards
