摘要

小腦橋腦角之轉移性惡性腫瘤為一少見之疾病，其原發部位多為乳房或肺部；本例為一延遲診斷之小腦橋腦角之原發部位不明之轉移性腺癌，患者以突發性單側顏面神經麻痺為初始表現，並以此為單一表現長達兩年餘；而後發生同側聲帶麻痺，但仍未被診斷出，直至發生同側第9、第10及第11對顱神經麻痺後，才予以安排頭部核磁共振影像檢查，發現一小腦橋腦角腫瘤，手術後證實為一轉移性腺癌。臨床上，我們對於持續性顏面神經麻痺的病患，要保持警覺心，將腫瘤納入鑑別診斷。

Metastatic tumors in the cerebellopontine angle (CPA) are rare. These uncommon secondary malignant deposits arise mostly from primary disease in the breast or lung. A case of metastatic adenocarcinoma of unknown origin affecting the CPA is described. In this case, unilateral persistent facial palsy of sudden onset was the only sign in the first two years, followed by ipsilateral vocal palsy. No definitive diagnosis was made until a head MRI was arranged when another three cranial nerves, the 9th, 10th, and 11th, devel-oped paralysis. Image study revealed a small CPA tumor, which was surgically removed and found to be a metastatic adenocarcinoma. Thus, idiopathic persistent facial palsy may arise the suspicion of a metastatic neoplasm in the cerebellopontine angle.
