was changed:
Accumulation of FDG in central venous catheter mimicking lymph node metastasis in PET imaging(PET CT)
Body
was changed:
Differential for intense FDG activity in the port includes infection, inflammation, FDG stasis, FDG emboli, and thrombus which can be either FDG-avid or photopenic.
Caveat: Avoidavoid FDG injection via a port as much as possible.

Caption
was removed:
Findings
was changed:
PET CT showing an FDG avid lesion in Rightthe right atrium at the tip of the port-a-cath with no anatomic abnormality seen on the corresponding CT images.
HeThe patient received his radiotracer into the port-a-cath as he hadtheir was poor intravenous access.
This should not be called a metastasis.
