The Tolosa-Hunt syndrome is an uncommon disease, described as an idiopathic granulomatous inflammation of the cavernous sinus or the superior orbital fissure. Its diagnosis is based on the presence of unilateral ophtalmoplegia associated with the enlargement and the enhanced contrast of the affected cavernus sinus in the MRI. We present the case of a 23-year-old man with ophthalmoplegia of the left eye, who was admitted to the Hospital Universitario del Valle. After performing extensive diagnostic studies, the Tolosa-Hunt syndrome was considered the cause of symptoms.
