title: New axillary lymph nodal F-18 fluoro-deoxy glucose uptake in an interim positron emission tomography scan - not always a sign of disease progression.
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.
