An 83-year-old man with hepatitis C presented to the hospital for follow-up imaging to monitor a thoracic aortic aneurysm. On examination, he was asymptomatic. Laboratory tests showed bicytopenia. Non-contrastenhanced computed tomography (CT) described no change in size of the thoracic aortic aneurysm but an incidental splenic lesion (figure 1A). Contrast-enhanced CT scan revealed a hypodense, well-defined and mild contrastenhancing lesion in the spleen (figure 1B).
