[Glomic tumour and its diagnostic interest. A clinical case]

Paragangliomas are tumours derived from cells in the neural crest that are normally benign, and have low incidence and slow growth rates. We report the clinical case of a 61 year-old female studied at the ENT's surgery suffering from a left side tinnitus with four years of evolution. Complementary explorations were carried out such as an audiogram, computerised axial tomography scans and angioresonance. In spite of the high diagnosis suspection, it is late confirmed, because it was not visible in the radiographic studies. We revised the literature referring this pathology.
