Tumores glômicos do osso temporal: relato de 6 casos

Abstract

The authors review the clinical, radiological and pathological features of 6 cases of glomus tumors of the temporal bone. Out of the 6 patients, 5 were female; age was distributed between 22 and 76 years (mean 48 years). The main clinical features were hypoacusia, tinnitus and otoscopic findings suggestive of the diagnosis. In one case was noted the concomitant presence of a neurinoma of the VIII cranial nerve with a ipsilateral glomus tumor, and in another case there was a concomitancy of carotid body tumor with temporal glomus jugularis tumor. Metastases were not observed in any case. Tumoral lesions were successfully ressected employing microsurgical techniques and a multidisciplinary staff involving neurosurgeons, head and neck surgeons and otolaryngologists. Radioteraphy was not employed, neither pre-operative embolization. Some aspects related to the nosology, embriology, pathophysiology, diagnosis and treatment of this interesting type of neoplasms are discussed.
