안면신경마비로 발현한 측두골의 전이성 폐 선암종 1예

Abstract

Metastatic lesions in temporal bones were rare in the past, however, nowadays, they seem to be increasing. The primary sites ofmetastases to the temporal bones are known to be the breasts, lungs, kidneys, gastrointestinal tract, prostate gland, larynx, andthyroid gland. We present a case with peripheral facial paralysis as the only symptom of a metastasis to the temporal bone in a73 year-old woman, and that peripheral facial paralysis was the first and only metastatic symptom in that case. This patient wasinitially diagnosed with Bells palsy. However, based on the pathologic findings, a further study revealed an adenocarcinoma ofthe lungs which spread to the temporal bone. Any metastatic diseases to the temporal bone should be considered as possibleetiology in patients with a clinical history of malignant neoplasms presenting with common otologic or vestibular symptoms,especially with facial nerve paralysis.
