Long-term cure of Tolosa-Hunt syndrome after low-dose focal radiotherapy.

Tolosa-Hunt syndrome (THS) is a rare cause of painful ophtalmoplegia due to chronic granulomatous inflammation of the cavernous sinus. While corticoids are the treatment of reference, corticodependence and corticoresistance are frequent, hence radiotherapy has been proposed as an alternative treatment. We report a case of long-term improvement (8 years) of THS after low-dose (20 Gy) radiotherapy in a patient with recurrences and corticodependence.
