title: A case review of the MRI features in alternating Tolosa-Hunt syndrome.
abstract: Tolosa-Hunt syndrome (THS) consists of a painful ophthalmoplegia with typical features in magnetic resonance imaging (MRI). The recurring nature of this affliction has been known since its first description. However, compromise of the contralateral cavernous sinus, known as alternating THS, is very rare and has never been examined using MRI. We report clinical data, laboratory data and imaging features of a patient with alternating THS. According to our literature review, this is the first MRI study of THS.
