Recurrent Tolosa-Hunt syndrome with normal neuroimaging. A report of three cases
INTRODUCTION. Tolosa-Hunt syndrome is caused by an unspecific inflammation in the cavernous sinus or superior orbital fissure. Recurrence occurs in 40% of cases. Magnetic resonance (MR) of the head and orbital phlebography can reveal characteristic data, although diagnosis is reached by exclusion according to International Headache Society criteria. Corticoids are the preferred treatment, since their use gives rise to the disappearance of the clinical condition in a few days. CASE
REPORT. We describe the cases of three patients with recurrent Tolosa-Hunt syndrome and MR images of the head with normal contrast. Case 1: a 52-year-old male with paralysis of the oculomotor nerve with recurrence on the contralateral side. Case 2: a 42-year-old female with recurrent paralysis of the abducent nerve. Case 3: a 34-year-old male with involvement of the oculomotor nerve, optic nerve and the first branch of the trigeminal nerve with recurrence of the ophthalmoplegia. In all cases the clinical symptoms disappeared with the use of corticoid therapy.
