An 8-year-old girl with left ptosis and diplopia for 1 day presented with a history of transient left periorbital headache 3 days before her visit. In the left eye, elevation, depression, and adduction movements were impaired ([Fig. 1]) and diplopia was omnidirectional, indicating oculomotor and abducens nerve palsy. Contrast-enhanced magnetic resonance imaging (MRI) revealed an abnormal contrast effect within the left cavernous sinus ([Fig. 2A–D]). Blood tests and cerebrospinal fluid examination showed no abnormalities; infection, tumor markers, and autoantibodies were negative. Based on the International Classification of Headache Disorders (3rd edition, β version) diagnostic criteria for Tolosa–Hunt syndrome (THS),[1] the patient was diagnosed with THS ([Table 1]). Methylprednisolone therapy was administered 7 days after disease onset, causing rapid paralytic improvement. One year after onset, contrast-enhanced MRI revealed a reduced abnormal contrast effect ([Fig. 2E, F]), with no disease recurrence for >3 years.

Description

Unilateral orbital pain associated with paresis of one or more of the IIIrd, IVth, and/or VIth cranial nerves caused by a granulomatous inflammation in the cavernous sinus, superior orbital fissure, or orbit

Diagnostic criteria

A

Unilateral headache fulfilling criterion C

B

Both of the following

1. Granulomatous inflammation of the cavernous sinus, superior orbital fissure or orbit, demonstrated by MRI or biopsy

2. Paresis of one or more of the ipsilateral IIIrd, IVth and/or VIth cranial nerves

C

Evidence of causation demonstrated by both of the following

1. Headache has preceded paresis of the IIIrd, IVth, and/or VIth nerves by ≤2 wk, or developed with it

2. headache is localized around the ipsilateral brow and eye

D

Not better accounted for by another ICHD-3 diagnosis

Abbreviations: ICHD-3, International Classification of Headache Disorders (3rd edition); MRI, magnetic resonance imaging.

THS is a painful ophthalmoplegia caused by nonspecific granulomatous inflammatory lesions of the cavernous sinus.[1] [2] Its estimated incidence is 1 patient per 1 million adults,[3] and it is even rarer in children.[2] [4] Immediate contrast-enhanced MRI targeting the cavernous sinus should be considered in cases with unilateral periorbital headache, even if transient and ipsilateral cranial nerve attacks.
