Tolosa-Hunt syndrome is characterized by painful ophthalmoplegia due to idiopathic granulomatous inflammation of the cavernous sinus. Steroid therapy dramatically reverses the symptoms and clinical signs. Because they also may respond to steroids, tumors such as lymphoma and meningioma and orbital tumors can make differential diagnosis difficult. ⋯ When faced with a clinical picture suggestive of the existence of Tolosa-Hunt syndrome clinical workup is mandatory and should lead to diagnosis of exclusion.
