Abstract:
Malignant leptomeningeal metastases involving both internal auditory canals (IACs) are rare and can mimic neurofibromatosis type 2 (NF2). Rapid progression of symptoms and involvement of facial nerve are characteristic clinical courses in contrast to the slow progression of symptoms in NF2. We report a rare case suspected to be metastatic tumor involving bilateral IACs, and presenting sudden bilateral hearing loss in a patient who was previously treated for adenocarcinoma of lung.
