Lymphoma with recent PET showing a new neck lesion. There is an enhancing nodule in the left prestyloid parapharyngeal space that measures 8 x 12 mm in axial cross-section. There is no significant lymphadenopathy in the neck otherwise. The thyroid and major salivary glands are unremarkable. The major cervical flow voids are intact. The osseous structures are unremarkable, aside from mild lower cervical spine degenerative spondylosis. The airways are patent. The imaged intracranial structures are unremarkable. There is mild scattered paranasal sinus mucosal thickening.
A left parapharyngeal lesion may represent a manifestation of lymphoma.
