Jugulo-tympanic glomus tumors or paragangliomas originate from neural crest cells and represent a low number of head and neck tumors (0.5%). Its slow growth and progressive symptoms cause the diagnosis to be delayed. The knowledge of the clinic that frequently involves unilateral hearing loss, pulsatile tinnitus and cranial nerve involvement can help to suspect the diagnosis. Different types of diagnostic methods are helpfun, as well as new treatment options have been proposed. Given the location and its important vascularization, there are cases in which open surgery is highly risky and alternative therapeutic procedures trying to reduce complications and morbidities in these patients need to be considered, as well as endovascular procedures. This article discusses the case of a 31-year-old female with an insidious onset of progressive left hearing loss, left pulsatile tinnitus and dysphonia. In 2013, nuclear magnetic resonance imaging was performed and a tumor infiltrative process suggesting paraganglioma was observed. Endovascular embolization was performed with onyx of jugulotympanic glomus on four occasions, with follow-up every 6 months, due to the size and location of the mass and its unresectable condition the tumor was considered non surgically resectable.
