Case ReportsGranulomatous pachymeningitis around the sella turcica (Tolosa-Hunt syndrome) involving the hypophysis--case report.
A 50-year-old female presented with right painful abducens nerve palsy persisting for 4 months and mild panhypopituitarism with diabetes insipidus for 6 months. T(1)-weighted magnetic resonance (MR) imaging of the sellar region showed a homogeneously enhanced mass lesion in the right cavernous sinus which seemed to extend from the swollen pituitary gland. T(2)-weighted MR imaging clearly showed the mass in the right cavernous sinus and the thickened dura mater of the sellar floor as hypointense, and the enlarged pituitary gland as isointense. ⋯ Corticosteroid therapy was begun after the biopsy. Her periorbital pain and diplopia were relieved, but diabetes insipidus persisted. Follow-up MR imaging showed a decrease in the volumes of the pituitary gland and the mass in the cavernous sinus.
