Abstract

A 58-year-old man was referred for an F-18 FDG PET study to evaluate for malignancy after thoracentesis demonstrated a hemorrhagic, lymphocyte- predominant exudative effusion. The PET scan demonstrated right paratracheal uptake suspicious for adenopathy, yet the CT scan did not show enlarged lymph nodes. A coiled central line was noted in the superior vena cava (SVC). Repeat PET imaging with injection through a peripheral line failed to demonstrate the abnormality, confirming the artifactual nature of the uptake. The use of central lines for tracer injection could lead to artifacts and, therefore, should be avoided.
