DESCRIPTION |
Unilateral orbital or periorbital pain associated with paresis of one or more between the 3rd, 4th and/or 6th cranial nerves caused by a granulomatous inflammation in the cavernous sinus, superior orbital fissure or orbit |
Repeated attacks of paresis of one or more ocular cranial nerves (commonly the 3rd), with ipsilateral headache |
DIAGNOSTIC CRITERIA |
A. Unilateral orbital or periorbital headache fulfilling criterion C |
A. At least two attacks fulfilling criterion B |
B. Both of the following: |
B. Both of the following: |
1. granulomatous inflammation of the cavernous sinus, superior orbital fissure or orbit, demonstrated by MRI or biopsy |
1. unilateral headache |
2. ipsilateral paresis of one, two or all three ocular motor nerves |
2. paresis of one or more of the ipsilateral the 3rd, 4th and/or 6th cranial nerves |
C. Orbital, parasellar or posterior fossa lesion has been excluded by appropriate investigation |
C. Evidence of causation demonstrated by both of the following: |
D. Not better accounted for by another ICHD-3 diagnosis |
1. headache is ipsilateral to the granulomatous inflammation |
2. headache has preceded paresis of the the 3rd, 4th and/or 6th nerves by ≤ 2 weeks, or developed with it |
D. Not better accounted for by another ICHD-3 diagnosis |
COMMENTS |
Some reported cases of Tolosa-Hunt syndrome had additional involvement of the 5th nerve (commonly the first division) or optic, 7th or 8th nerves. Sympathetic innervation of the pupil is occasionally affected |
Some data suggest that headache can develop up to 14 days prior to ocular motor paresis |
Gadolinium enhancement or nerve thickening can be demonstrated using MRI |
Careful follow-up is required to exclude other causes of painful ophthalmoplegia such as tumours, vasculitis, basal meningitis, sarcoid or diabetes mellitus |
Pain and paresis of Tolosa-Hunt syndrome resolve when adequately treated with corticosteroids |
