Popis: Facial nerve neurinoma is less common than trigeminal nerve and acoustic nerve neurinomas. Recently, reported cases of facial nerve neurinoma have increased due to progress in the diagnostic imaging. We report two cases of facial nerve neurinoma. Case 1 is a 45-year-old man. In June, 1997, he noted dripping of water from the right side of his mouth. A complete right facial palsy was observed on his first visit. He was diagnosed as having facial nerve neurinoma with CT, MRI and a biopsy with a fine needle aspiration. Case 2 is a 64-year-old man. In September, 1998, he noticed disturbance of right facial mov ement. A complete facial palsy developed upon his first visit. He was diagnosed as having facial nerve neurinoma with CT, MRI and a biopsy with a fine needle aspiration. Even though facial nerve neurinoma is a benign tumor, CT findings are not consistent and hard to interpret. MRI provides images more compatible with neurinoma. We concluded that MRI is a valuable addition to diagnose facial nerve neurinoma.
