Intensity modulated conformal radiotherapy of a jugulo-tympanic paraganglioma

Jugulo-tympanic paragangliomas are rare benign tumors arising from the neuroectodermal cells of the tympanic cavity and the dome of the jugular vein. Surgical resection has long been the first-line treatment. However, when this is not possible, radiotherapy remains a therapeutic alternative allowing local control with less morbidity. We report the case of a patient with an unresectable tympano-jugular paraganglioma, the symptomalagy was dominted by chronic headaches and right sided hypoacousie, and the treatment consisted of external radiation therapy with a total dose of 50 Gy in 25 fractions, one fraction per day, 2 Gy per fraction using the IMRT technique. The evolution was good with disappearance of clinical symptomatology, significant local control with less toxicity.
