Abstract

Leptomeningeal carcinomatosis (LMC) occurs in 3 to 5% of all cancers and can be found in up to 25% of all lung cancers (1). Unilateral and, to a greater extent, bilateral metastases to the internal auditory canal (IAC) in the setting ofLMC are extremely uncommon; worldwide, only a few cases have been reported in patients with known metastatic lung adenocarcinoma (2,3). However, initial presentation of metastatic lung adenocarcinoma with bilateral metastases to the IAC to this date has not been reported. This article reports a case of a 64-year-old man presenting with headache, otalgia, hearing loss, disequilibrium, and facial nerve paralysis (FNP) caused by intracerebral metastases from lung adenocarcinoma mimicking bilateral vestibular schwannomas (VSs). The Central Denmark Region Committees on Health Research Ethics provided an exemption for this report.
