Introduction. Tolosa?Hunt syndrome (THS) is a rare entity, characterized by unilateral orbital pain associated with paresis of one or more of the oculomotor cranial nerves and caused by a granulomatous inflammation in the cavernous sinus, superior orbital fissure or orbit. The low prevalence of THS with a broad spectrum of other disorders that could cause painful ophtalmoplegia resulted in a stricter diagnostic criteria of THS in the latest edition of the International Classification of Headache Disorders. Current criteria require demonstration of granuloma by magnetic resonance imaging or biopsy. The diagnosis could be difficult and the initiation of treatment delayed due to a high variablity of clinical presentation of TSH. Reducing the number of patients that, based on clinical presentation, could be classified as having THS, but do not fullfil all diagnostic criteria further complicates establishing of correct diagnosis. Case report. Hereby we presented eight patients diagnosed with and treated for THS. Inspite the exclusion of other causes of painful ophtalmoplegia, granuloma could not be demonstrated in a half of patients. Clinical presentation of THS in patients with and without shown granuloma, did not significantly differ concerning headache characteristics (localization, intensity, quality, duration preceding cranial nerve palsy, response to steroids), the affected cranial nerve, disease course and response to the treatment, as well as types of diagnostic procedures that were performed in ruling out other diseases from the extensive differential diagnosis of painful ophthalmoplegia. Conclusion. There is no significant difference between the THS patients with and without demonstrated granuloma. nema
