Bladder cancer is the second most commonly occurring cancer of the genitourinary tract. Transitional carcinoma of the bladder, the most prevalent type, is very aggressive and can metastasize early (1). The most frequent sites of bladder cancer metastases are the lymph nodes, liver, lung, bone, and adrenal gland. Bladder cancer is rarely reported to metastasize to the temporal bone (1% of cases) (2). The most common primary tumors that metastasize to the temporal bone are breast (10%), lung (6%), and prostate (5%). In this study, a case of metastatic tumor of the temporal bone from transitional cell carcinoma of the bladder will be presented.
