The combined symptoms of vertigo, hearing loss, and facial palsy indicate the presence of lesions in the internal auditory canal (IAC). Differential diagnoses, such as inner/middle ear infections and IAC neoplasms, can make the definitive diagnosis of IAC lymphomas challenging. Lymphomas can infiltrate the central nervous system at various sites; however, IAC involvement in metastatic lymphomas is very rare. Herein we report the case of a patient with IAC lymphoma presenting with aural fullness of the left ear and intractable otalgia followed by symptoms of facial weakness, hearing loss, and vertigo within 48 h. The uncharacteristic clinical manifestations and concurrent middle ear infection meant that the conclusive diagnosis of IAC lymphoma was delayed.
眩晕、听力丧失和面神经麻痹的综合症状表明内耳道（IAC）存在病变。诸如内耳/中耳感染和IAC肿瘤等鉴别诊断会使IAC淋巴瘤的明确诊断具有挑战性。淋巴瘤可在多个部位浸润中枢神经系统；然而，转移性淋巴瘤累及IAC非常罕见。在此，我们报告一例IAC淋巴瘤患者的病例，该患者最初表现为左耳耳闷和顽固性耳痛，随后在48小时内出现面部无力、听力丧失和眩晕症状。不典型的临床表现以及并发的中耳感染导致IAC淋巴瘤的最终诊断延迟。
