Tolosa-Hunt syndrome Totally Explained

Everything about Tolosa-hunt Syndrome totally explained

Tolosa-Hunt syndrome (THS) is a rare disorder characterized by severe and unilateral headaches with extraocular palsies, usually involving the third, fourth, fifth, and sixth cranial nerves, and pain around the sides and back of the eye, along with weakness and paralysis (ophthalmoplegia) of certain eye muscles.
In 2004, the International Headache Society provided a definition of the diagnostic criteria which included granuloma.

Causes

The exact cause of THS isn't known, but the disorder is thought to be, and often assumed to be, associated with inflammation of the areas behind the eyes (cavernous sinus and superior orbital fissure).

Signs and Symptoms

Symptoms are usually limited to one hemisphere of the brain, and in most cases the individual effected will experience intense, sharp pain and paralysis of muscles around the eye. Symptoms may subside without medical intervention, yet recur without a noticeable pattern.
In addition, affected individuals may experience paralysis of various facial nerves and drooping of the upper eyelid (ptosis). Other signs include double vision, fever, chronic fatigue, verigo or arthralgia. Occasionally the patient may present with a feeling of protrusion of one or both eyeballs (exophthalmos).

Prognosis

The prognosis of THS is usually considered good. Patients usually respond to corticosteroids, and spontaneous remission can occur, although movement of ocular muscles may remain damaged. Roughly 30%-40% of patients who are treated for THS experience a relapse.

Epidemiology

TSA is uncommon in both the United States and internationally. Both genders, male and female, are affected equally, and typically occurs around the age of 60.Further Information
