摘要：
A 38-year-old woman with exertional dyspnea and decreased ejection fraction underwent F-18-FDG PET/CT, which showed extraordinarily high FDG uptake in a catheter-related thrombus formed along a central venous catheter. The thrombus's uptake (SUVmax, 127.3) was comparable to or greater than uptake seen in the bladder's urine. This abnormal uptake was unusual for thrombi, suggesting additional factors like undiluted FDG solution stasis due to a fibrin sheath formation around the catheter and first-pass effect. A new peripheral venous route should be secured to administer FDG in case of suspected catheter-related thrombus to avoid potential complications including a pulmonary embolism.
