[Insidious hearing loss and facial palsy as the presenting symptoms of meningeal carcinomatosis resulting from adenocarcinoma of the lung].
An 80-year-old man was admitted to our hospital with a complaint of insidious hearing loss and facial palsy. Chest X-ray film showed an abnormal shadow in the right lower lobe. Adenocarcinoma of the lung was diagnosed by transbronchial brushing cytology. During admission, headache and dysphagia appeared, although no abnormality was detected in the brain CT and MRI. Lumbar puncture yielded adenocarcinoma cells in the cerebrospinal fluid. A diagnosis of leptomeningeal metastasis from the adenocarcinoma of the lung was considered and intrathecal administration of methotrexate was performed. The patient's condition deteriorated gradually and he died of respiratory failure. Autopsy revealed massive invasion of tumor cells in the leptomeninges of the brain and spinal cord. This case illustrates that facial nerve palsy with insidious hearing impairment may appear as the initial symptoms in meningeal carcinomatosis resulting from lung cancer metastasis.
