Nasopharyngeal cancer, status post RT, surveillance. Again seen are post-treatment findings in the neck without discrete mass to suggest recurrent nasopharyngeal tumor. There is no evidence of significant cervical lymphadenopathy based on size criteria. The thyroid and major salivary glands are unremarkable. The major cervical arterial flow voids appear to be intact. No suspicious osseous lesions. There is T1 shortening involving the skull base and upper cervical spine likely reflecting post radiation change. The imaged intracranial structures are unremarkable. There is diffuse opacification of the sphenoid sinuses and right worse than left posterior ethmoid air cells. There is also mild right anterior ethmoid opacification as well as a tiny fluid level within the left maxillary sinus.. These findings are significantly progressed since prior.
1. Post-treatment findings in the neck without measurable residual nasopharyngeal tumor. No significant cervical lymphadenopathy.2. Interval increase in paranasal sinus opacification, particularly the sphenoid sinus and posterior ethmoid air cells bilaterally.
