유방암의 측두골 전이에 의한 안면신경마비 1예

Metastasis to the temporal bone is rare. Tumors of breast, lung, kidney, gastrointestinal track, larynx, and prostate gland are the most common site of temporal bone metastasis. The pathogenesis of spread to the temporal bone is most commonly by the hematogenous route. Here is a report on a case of breast carcinoma presenting with facial paralysis for 1 week and ear fullness for 1 month. The patient was initially diagnosed as Bell’s palsy, and later the clinical impression was revised to metastatic breast carcinoma to temporal bone, based on the pathologic finding. Metastatic disease should be considered as a possible etiology in patient with a clinical history of malignant neoplasms presenting with facial nerve paralysis.
