A case of Tolosa-Hunt syndrome affecting both the cavernous sinuses and the hypophysis, and associated with C3 and C4 aneurysms.
BACKGROUND
We describe the first case of Tolosa-Hunt syndrome that is associated with C3 and C4 aneurysms.


METHODS
The patient, a female aged 58 years, had diplopia and right retroorbital pain. Magnetic resonance imaging revealed an enlargement of the hypophysis and bilateral cavernous sinuses, particularly on the right side. Cerebral angiography demonstrated ICA aneurysms of the left C3 and right C4 portions. These symptoms were immediately alleviated after initiation of prednisolone therapy, but recurred after the dose was tapered off. Radiological examination revealed an enlargement of the hypophysis whereas the right C4 aneurysm had decreased in size and no blood flow was apparent in the ipsilateral ophthalmic artery. A biopsy was performed and the results showed a focal inflammatory change. Steroid therapy was represcribed, and after a follow-up period of 10 months without therapy, the patient has been free of symptoms.


CONCLUSIONS
We conclude that bilateral ICA aneurysms might be directly induced by inflammatory infiltration into intracavernous ICAs.
