RADIOLOGY: HEPATOBILIARY: Case# 33703: LIVER ABSCESS. 76-year-old male with renal cell carcinoma of the right kidney. 1. Bilateral renal masses consistent with renal cell carcinoma. 2. Extensive, multi loculated or lobulated cystic liver mass. Given the lack of any such finding on the prior CT scans, a liver abscess is the most likely diagnostic considerations here. A source might very well be a presently quiescent diverticulitis. 3. Small right pleural effusion. 4. No evidence of adenopathy. 5. Post-surgical changes in the pelvis.
