We present the imaging findings of a 44-year-old female patient who was diagnosed with nasopharyngeal carcinoma (NPC) extending from the nasopharynx to the external auditory canal (EAC) through the Eustachian tube (ET). The patient presented with a left neck submandibular lump on initial presentation that showed NPC upon fine needle aspiration, leading to chemoradiotherapy. Despite treatment, the patient experienced multiple relapses and later presented with aural symptoms, including left ear pain, foul-smelling drainage, and trismus on recurrence, and was subsequently diagnosed through biopsy. CT, MRI, and PET-CT scans revealed an extensive infiltrative nasopharyngeal mass extending into the left ET, involving the EAC. This rare case highlights the importance of considering the extension of NPC into the EAC as a potential etiology in patients who present with aural symptoms.
我们展示了一名44岁女性患者的影像学检查结果，该患者被诊断为鼻咽癌（NPC），肿瘤通过咽鼓管（ET）从鼻咽部延伸至外耳道（EAC）。患者初诊时表现为左侧颈部下颌下肿块，细针穿刺显示为鼻咽癌，随后接受了放化疗。尽管进行了治疗，患者仍多次复发，后来出现耳部症状，包括左耳疼痛、恶臭分泌物以及复发时的牙关紧闭，随后通过活检确诊。CT、MRI和PET-CT扫描显示，鼻咽部有广泛浸润性肿块延伸至左侧咽鼓管，累及外耳道。这个罕见病例凸显了在出现耳部症状的患者中，将鼻咽癌延伸至外耳道视为潜在病因的重要性。
