Abstract
Purpose:To highlight the role of constructive interference steady state (CISS) magnetic resonance imaging (MRI) in the diagnosis of Tolosa-Hunt Syndrome (THS).Case Report:We describe a case of THS in a 55-year-old woman presenting with left painful opthalmoplegia that was diagnosed by CISS MRI. Patient responded to steroid treatment and the lesion resolved.Conclusion:Imaging with MRI can help in making the diagnosis of THS by demonstrating an enhancing soft tissue lesion in the cavernous sinus and orbital apex resolving with steroids. CISS MRI is a sensitive sequence for diagnosis and follow-up imaging in THS.
Highlights
Painful ophthalmoplegia is caused by a number of lesions in the parasellar, cavernous sinus and orbital apex regions
Tolosa–Hunt syndrome (THS) was named after Tolosa and Hunt who separately described this condition as a granulomatous inflammation of the cavernous sinus and identified it to be steroid responsive.[1]
Modern imaging magnetic resonance imaging (MRI) made it possible to study the lesions in the cavernous sinus and orbital apex responsible for this syndrome and other causes of painful ophthalmoplegia with high precision.[2]
