초록
We report on a patient with brain metastasis involving bilateral internal auditory canalfrom non-small cell lung cancer (NSCLC). A 49-year-old woman who had been diagnosedwith NSCLC (T2aN1M0) complained of persistent vertigo and bilateral tinnitusfor three months. The patient had refused all treatments, including surgery andchemotherapy; however, she sought alternative medicine. The patient’s hearing lossshowed rapid progression bilaterally, and rotatory vertigo with peripheral-type nystagmusdeveloped. Magnetic resonance imaging of the brain showed irregular nodularenhancement within both internal auditory canals with leptomeningeal enhancementand multiple intracranial metastasis. The patient was treated with epidermal growthfactor receptortyrosine kinase inhibitor, and the tumor showed partial response. Thiswas a rare case of multiple brain metastases involving bilateral internal auditory canalfrom known NSCLC presenting with vertigo and hearing loss.
Abstract
We report on a patient with brain metastasis involving bilateral internal auditory canalfrom non-small cell lung cancer (NSCLC). A 49-year-old woman who had been diagnosedwith NSCLC (T2aN1M0) complained of persistent vertigo and bilateral tinnitusfor three months. The patient had refused all treatments, including surgery andchemotherapy; however, she sought alternative medicine. The patient’s hearing lossshowed rapid progression bilaterally, and rotatory vertigo with peripheral-type nystagmusdeveloped. Magnetic resonance imaging of the brain showed irregular nodularenhancement within both internal auditory canals with leptomeningeal enhancementand multiple intracranial metastasis. The patient was treated with epidermal growthfactor receptortyrosine kinase inhibitor, and the tumor showed partial response. Thiswas a rare case of multiple brain metastases involving bilateral internal auditory canalfrom known NSCLC presenting with vertigo and hearing loss.
