Neuro-ophthalmic and otologic manifestations can also occur. Isolated otologic presentations of nasopharyngeal cancer are rare and the diagnosis of nasopharyngeal cancer may not be foremost in the list of differentials. Case presentation We present the case of a 29-year-old Nigerian woman with bilateral conductive hearing loss and tinnitus after air travel. There were no other symptoms. The persistence of the symptoms after adequate treatment for otitic barotrauma necessitated re-evaluation which led to a diagnosis of nasopharyngeal cancer. Conclusion Isolated otologic manifestations of nasopharyngeal cancer are rare in regions with low incidence of the disease. There is a need for it to be considered as a possible differential in patients presenting with bilateral serous otitis media. Introduction The clinical presentations of nasopharyngeal cancer may sometimes be insidious and nonspecific. They are usually related to the local regional and distant spread or metastasis of the lesion. They may include cervical lymphadenopathy nasal blockage epistaxis hyponasal speech and otologic and neuro-ophthalmic manifestations 1 . The clinical morphology of the lesion may be infiltrative ulcerative or exophytic. The otological manifestations of this disease entity are commonly unilateral Eustachian tube dysfunction fluid accumulation within the middle ear conductive hearing loss otalgia and tinnitus 2 . However these presentations are not pathognomonic of nasopharyngeal cancer. It is quite uncommon for nasopharyngeal cancer .
