Reidel's thyroiditis and Tolosa-Hunt syndrome, a rare association.

A previously undescribed association of Reidel's thyroiditis with Tolosa-Hunt syndrome is reported. A 33 year-old Caucasian female presented with a two-year history of painful progressive goitre, histologically a Reidel's thyroiditis. She underwent left partial thyroidectomy. Post-operatively she developed severe right retro-orbital pain, right temporal headache and a partial right occulomotor nerve palsy. A diagnosis of Tolosa-Hunt syndrome was made. Some important aspects of this case are discussed.
