Positron emission tomography - computed tomography (PET-CT) with fluorine-18-fluorodeoxy-d-glucose (¹⁸F-FDG) has an increasing role in head and neck imaging. Interpretation of ¹⁸F-FDG-tracer uptake in the head and neck requires an understanding of normal physiological patterns of tracer uptake, as well as knowledge of potential pitfalls and atypical patterns. This article presents a select series of unusual patterns of ¹⁸F-FDG uptake on PET-CT imaging of the head and neck.
