title: Actinomycosis Mimicking Tolosa-Hunt Syndrome in a 6-Year-Old Boy: Case Report.
abstract: Tolosa-Hunt syndrome is an idiopathic inflammatory process of the cavernous sinus or orbit manifesting as painful ophthalmoplegia. In this report, we detail the case of a 6-year-old boy who presented with several weeks of unilateral headache and diplopia. He was found to have an infiltrative process involving the bilateral cavernous sinuses and pituitary gland on MRI. Given a progressing infiltrative central nervous system process on repeat MRI and the development of cerebral salt wasting, a biopsy was performed revealing actinomycosis. To our knowledge, this is the first reported case of actinomycosis masquerading as Tolosa-Hunt syndrome in a child.
