Finally, an 18-fluorodeoxyglucose (FDG)-positron emission tomography (PET)-CT scan was performed, which demonstrated multiple focal areas of abnormally high FDG uptake within the spleen (Figures 2, 3), which were not identifiable on CT scan images (non-contrast CT and contrast-enhanced images) (Figure 4).
Fused fluorodeoxyglucose-positron emission tomography-CT (axial and coronal) images showing multiple focal fluorodeoxyglucose-avid nodular lesions in spleen.
