Inadvertent 2-deoxy-2-[18F]fluoro-D-glucose lymphoscintigraphy: a potential pitfall characterized by hybrid PET-CT.

Abstract

PURPOSE: To communicate an important pitfall in positron emission tomography (PET) oncologic staging using 2-deoxy-2-[18F]fluoro-D-glucose (FDG). PROCEDURE: A 60-year-old man with a right upper lobe bronchogenic carcinoma was injected with FDG through a cannula in his left cubital fossa, with a small amount of the dose extravasating. RESULTS: Images obtained one hour post-injection with a positron emission tomography-computerized tomography (PET-CT) scanner demonstrated linear FDG activity running with the left arm brachial vascular bundle and along collateral channels, and accumulation of FDG in a low left axillary lymph node of normal size and CT appearance. CONCLUSIONS: Following inadvert..
