Abstract
Fluoro-deoxy glucose (FDG) is a non-specific tracer and may accumulate in non-malignant conditions causing potential pitfalls leading to false-positive interpretations of interim positron emission tomography scan. We report a case of a potential pitfall of false-positive axillary lymph nodal F-18 FDG uptake caused by injection extravasation.
摘要
氟代脱氧葡萄糖（FDG）是一种非特异性示踪剂，可能在非恶性情况下积聚，导致潜在的陷阱，从而对中期正电子发射断层扫描产生假阳性解读。我们报告一例因注射外渗导致腋窝淋巴结F-18 FDG摄取假阳性的潜在陷阱病例。
