FDG-PET/CT is widely used for the diagnosis of head and neck lesion. The usefulness of FDG PET/CT is known for a recurrence diagnosis and the curative effect judgment of head and neck tumor. The physiological accumulation of FDG to laryngopharynx, salivary gland and muscles is frequently seen. Moreover, we often see inflammatory FDG accumulation for lymph node. Therefore, the differentiation of malignant tumor and non-malignant lesion is difficult. Some cases are misdiagnosed by the accumulation of normal structure and the reactive change. It may occur overestimation of FDG accumulation for non-malignant lesion. In this report, we present some cases of FDG-PET/CT in the head and neck region that is difficult to distinguish malignancy and non-malignancy.
