59-year-old female with diffuse large B cell of the sinus status post 4 cycles of chemotherapy. There is redemonstration of soft tissue density within the maxillary sinus immediately posterior to the anterior wall of the left maxillary sinus. This soft tissue prominence again extends posteriorly and posterior laterally to the left maxillary sinus and along the enlarged infraorbital nerve groove. The osseous involvement of the anterior aspect of the maxillary sinus, including a mixed sclerotic and lucent area, appears unchanged. There is increased mucosal thickening and opacification of both maxillary sinuses. This appearance may be due to chronic sinus disease, although lymphomatous involvement cannot be excluded. MRI may be more helpful in delineating tumor from inflammatory disease. Opacification of the left frontal and bilateral ethmoid sinuses, as well as mucosal thickening of the right sphenoid sinus is also noted. The retro-orbital fat remains within normal limits. Extraocular musculature and globe remain within normal limits. No definitive abnormality of cavernous sinus or Meckel's cave on this exam is detected. Limited view of nasopharynx demonstrates no abnormality.
Persistent abnormal soft tissue within the left maxillary sinus with associated osseous changes as detailed. Increased pan-sinus opacification. MRI may be more helpful in delineating tumor involvement from inflammatory disease.
