A 76-year-old woman presented with a 1-year history of worsening dysphagia and throat discomfort. Her medical, surgical, and family histories were noncontributory. Magnetic resonance imaging (MRI) revealed a 5-cm, well-circumscribed, ovoid, soft tissue mass located in the prestyloid compartment of the right parapharyngeal space (Figure 1, sagittal T1-weighted contrast-enhanced image, arrow). The mass, which caused marked narrowing of the oropharyngeal air column, was radiologically heterogeneous; it was predominantly hyperintense but appeared focally and centrally hypointense on the T1-weighted images. The nasopharynx, hypopharynx, and parotid and submandibular glands were normal. No lymphadenopathy was present. The right carotid sheath structures were displaced posterolaterally but were otherwise unremarkable.
