Tolosa-Hunt syndrome with atypical intrasellar and juxtasellar lesions--two case reports.
Two patients with Tolosa-Hunt syndrome (THS) who had atypical lesions in the intrasellar and juxtasellar regions are reported. They manifested with painful ophthalmoplegia. Magnetic resonance imaging (MRI) commonly showed an increase in the volume of the cavernous sinus occupied by homogeneously well-enhanced lesions in both cases. These lesions extended to the intrasellar and juxtasellar regions with meningela enhancement. Follow-up MRI after steroid treatment demonstrated normalized or decreased size of the cavernous sinus. These findings suggested nonspecific inflammatory granulomatosis with atypical extension.
