Frontal sinus nasopharyngeal carcinoma recurrence masquerading as chronic frontal sinusitis: a case report
Tóm tắt
Recurrence of nasopharyngeal carcinoma (NPC) is still a worrying issue despite the advent and advancement of treatment strategies. Presentation of recurrent NPC is different from primary NPC and indicates poor prognosis. Frontal sinus metastasis without any involvement of other sinuses is very rare and could be mistaken as sinusitis or mucocele. Owing to its rare occurrence, it presents a great challenge for clinicians to make a prompt diagnosis. The background chronic rhinosinusitis symptoms as a result of irradiation for NPC may masquerade the underlying paranasal sinus recurrence.
