Abstract:
We report the positron emission tomography-computed axial tomography (PET-CT) appearance of the inflammatory involvement of the salivary glands of a 69-year-old female with a history of lymphoma and known primary Sjogren's syndrome. Hybrid PET-CT was performed 5 months after completion of chemotherapy using a Siemens Biograph scanner (Knoxville, TN) 45 minutes after intravenous administration of 15 mCi of F-18 fluorodeoxyglucose (FDG). CT transmission scan was obtained for attenuation correction. PET-CT demonstrated no evidence of hypermetabolic nodal disease but showed symmetric intensely hypermetabolic submandibular and parotid salivary glands.
