Large parapharyngeal mass. There is a well-defined right poststyloid parapharyngeal mass that measures up to approximately 5.5 cm. The tumor contains multiple prominent flow voids, has a "salt and pepper" appearance, and displaces the internal and external carotid arteries anteriorly. In addition, the right internal jugular vein is compressed by the tumor. The mass does not extend up to the skull base. There is narrowing of the oropharyngeal airway. There are multiple heterogeneously enhancing thyroid nodules, the largest of which measures up to 17 mm. There is a T2 hyperintense and enhancing nodule in the left parotid tail that measures up to 12 mm. The other major salivary glands are unremarkable. There is no evidence of significant cervical lymphadenopathy based on size criteria. There is mild degenerative spondylosis at C4-5 and C5-6. The imaged intracranial structures and orbits are unremarkable.
1. A right poststyloid parapharyngeal mass that measures up to approximately 5.5 cm likely represents a paraganglioma. 2. Multiple nonspecific thyroid nodules.3. Nonspecific nodule in the left parotid tail that measures up to 12 mm.
