Non-Hodgkin's lymphoma rarely occurs in extranodal head and neck simultaneously. A case originating from the maxillary sinus and parapharyngeal space is reported. A 77-year-old man had noticed a swelling on his hard palate for 6 weeks. Physical examination revealed an induration on the pharyngeal mucosa as well as a mass on the hard palate. CT and MR studies were performed to define the extent of these lesions. The lesion in the maxillary sinus occupied the cavity and had infiltrated the buccal mucosa, nasal cavity, infratemporal fossa and pterygoid muscles. The other lesion was situated in the parapharyngeal space and pharyngeal mucosal space. However, both modalities failed to identify any continuity between the two lesions. These findings suggested the two lesions might have occurred independently.
