Humans ; Vestibular Neuronitis/therapy*

A 77-year-old man visited our department because of dizziness from one month ago. Dizziness was continuous and non-whirling and this type of dizziness was the first time. He also complained of tinnitus and hearing impairment of the right ear. On physical examination, he showed spontaneous left-beating horizontal and torsional nystagmus and rightward head thrust was positive. He was admitted under the first impression of right vestibular neuritis. On inner ear MRI, there was a well-demarcated 2.5x2.3 cm sized mass of right cerebellopontine angle. This mass showed somewhat low signal intensity in both T1 and T2-weighted image and modest enhancement with Gadolinum. And approximately 4.5x3 cm sized mass could be seen in the simple chest roentgenogram. On chest CT, there was a poorly demarcated 3x2.5 cm sized mass in left lower lobe of lung. The patient was diagnosed as small cell lung cancer with brain metastasis by Per-Cutaneous Needle Aspiration of lung. In spite of radiotherapy and concurrent chemotherapy, he expired after 5 months.
