Potential Pitfall in the Assessment of Lung Cancer with FDG-PET/CT: Talc Pleurodesis Causes Intrathoracic Nodal FDG Avidity

<table>PET/CT images showing CT (A), PET (B), and fused images (C). There is an FDG avid and high-attenuation peridiaphragmatic lymph node (arrow) adjacent to a curvilinear area of FDG avid and high-attenuation pleural thickening. There is slight misregistration related to lateral excursion of the chest during respiration. A chest CT (D) performed prior to talc pleurodesis does not show any preexisting high-attenuation peridiaphragmatic lymph node.</table>
