case_images: (A) Maximum Intensity Projection (MIP) showing pathological [18F]FDG uptake in the pericardial cavity and right knee (red arrow) and [18F]FDG enhancement in the cephalic vein, possibly caused by a thrombophlebitis (blue arrow). Furthermore, physiological uptake can be seen in the liver, kidneys, and urinary catheter tract. (B-D) Coronal PET, low-dose CT, and PET/CT fusion image of the thorax, respectively, showing clear pericardial effusion (green arrow) with slightly elevated [18F]FDG uptake in the pericardial layers. The pleural effusion showed no tracer uptake. (E-G) Sagittal PET, low-dose CT, and PET/CT fusion image of the right knee (red arrow), respectively, showing increased [18F]FDG uptake in the synovial space due to the Hemophilus Influenza infection.

case_images: Furthermore, persisting pericardial fluid without [18F]FDG uptake was seen despite continuous drainage (Figures 1B-D). [18F]FDG enhancement was seen in the pericardial layers, mainly around the right atrium, most likely due to some remaining pericarditis (Figures 1A,B,D). However, some increased uptake in the pleural sheets could indicate pleuritis. [18F]FDG uptake was seen in the right cephalic vein indicating a possible thrombophlebitis (Figure 1A). In the synovial space of the right knee clear [18F]FDG enhancement was visible, indicating the earlier diagnosed synovitis (Figures 1A,E,G).
