ABSTRACT

Tumors of the jugular glomus are indolent, well vascularized lesions that cause symptoms through the massive effect on neighboring structures. Imaging studies reveal details about tumor extension and regional anatomy, essential in the planning of surgery. The main therapeutic modality is the surgical excision; other alternatives include radiotherapy and stereotactic radiosurgery. We report the case of a 62-year-old female patient with a 4-year progression with right pulsatile tinnitus, ipsilateral hearing loss and an episode of vertigo in whom the right otoscopic examination revealed a protruding lesion, which was hyperemic and pulsatil, we did imaging studies and biopsy in the operating room, the histopathologic result reported paraganglioma. The patient underwent linear acceleration stereotactic radiosurgery as the primary treatment, and has been kept under observation with magnetic resonance imaging controls, currently without significant tumor growth. Radiotherapy is an effective treatment of paragangliomas of the jugular glomus with a tumor control rate equivalent or even better than surgery. Recent data from the literature show that Gamma Knife, linear acceleration stereotactic radiosurgery and/or CyberKnife achieve good rates of tumor control and symptoms, ranging from 71% to 100% and 88% to 100%, respectively. Although the literature on the linear acceleration stereotactic radiosurgery for glomus jugulare is poor compared to that of Gamma Knife, the available results appear convincing.
