Pleomorphic Adenoma Simulating Metastatic Squamous Cell Carcinoma on F-18 Fluorodeoxyglucose Positron Emission Tomography

F-18 FDG has been demonstrated to be highly accurate in the staging of squamous cell carcinoma of the head and neck. A case of intensely abnormal FDG uptake within the parotid gland in a patient undergoing PET for staging of a laryngeal carcinoma was initially considered to be strongly suspicious of...

Description
Summary:F-18 FDG has been demonstrated to be highly accurate in the staging of squamous cell carcinoma of the head and neck. A case of intensely abnormal FDG uptake within the parotid gland in a patient undergoing PET for staging of a laryngeal carcinoma was initially considered to be strongly suspicious of metastatic disease. Fine-needle aspiration revealed the lesion to be a pleomorphic adenoma. This case highlights the fact that both benign and malignant lesions in the parotid gland may exhibit intense FDG activity and the need for pathologic confirmation of parotid gland lesions for accurate disease staging.
