Fig. 1From: Multimodality radionuclide imaging in fever of unknown origin presenting with a solitary spleen lesion18F-FDG PET/CT Whole Body (a), performed at patient's admission, demonstrated an area of increased tracer incorporation (SUVmax 6.1) in the spleen inferior pole (black arrow), associated with diffuse bone marrow uptake. Fused axial (b) and coronal (c) PET/CT slices well depicted focal 18F-FDG accumulation (white arrow) within a hypodense area in the inferior splenic pole, with no evidence of meaningful spleen enlargement (splenic length 11Â cm)Back to article page
