Female, 75 years old, with history of right nasopharyngeal carcinoma status post chemotherapy and radiation. Globular, nonenhancing soft tissue is redemonstrated in the right nasopharynx. Since the prior examination, areas of frank tissue loss have progressed. No masslike lesions are seen to suggest recurrent tumor.Ill-defined edema and hyperenhancement persist within the right parotid gland and masticator space. The salivary glands are otherwise unremarkable. No pathologic adenopathy is observed. The right mastoid air cells are largely opacified with mild partial opacification on the left. Mucous retention cysts are seen in both maxillary sinuses and there is progressive mucosal thickening on the left. Marrow signal abnormality persists within the clivus, anterior C1 arch, and odontoid process. The adjacent ligamentous structures are thickened. Multilevel cervical spondylosis is again seen.
1.Progressive necrosis and tissue loss along the right nasopharyngeal mucosal space is seen. No findings are evident to suggest recurrent tumor.2.No pathologic adenopathy is detected within the field-of-view of the examination.3.Treatment related findings involving the soft tissues of the right masticator space and parotid gland are unchanged. Likewise, marrow signal abnormality and thickening along the and C1-2 articulation are unchanged and likely treatment related.4.Progressive mucosal thickening is seen in the left maxillary sinus. Opacification of the mastoid air cells suggests Eustachian tube dysfunction.
