Painful ophthalmoplegia: a case report and literature review.

Painful ophthalmoplegia consists of periorbital or hemicranial pain with ipsilateral ocular motor nerve palsies. There are many etiologies of painful ophthalmoplegia. Tolosa-Hunt syndrome (THS) is an uncommon disease caused by non-specific inflammation of the cavernous sinus, superior orbital fissure and the apex of the orbit. A 45-year-old female reported episodes of reversible left eye pain and diplopia. Examination showed periorbital oedema and left palpebral semiptosis, paresis of the partial left third nerve palsy with normal pupillary reactions, fourth and sixth left cranial nerves, and hypoesthesia over the first and second division of the left trigeminal nerve. Blood analysis, postcontrast cranial and orbital magnetic resonance (MR) imaging, cranial MR angiography and CSF analysis demonstrated no abnormalities. The clinical diagnosis satisfies the criteria for THS. After steroid therapy her symptoms and clinical signs dramatically reverses. Painful ophthalmoplegia with inflammatory conditions such as THS is highly responsive to corticosteroids but should be diagnoses of exclusion. The THS diagnosis should be used rarely and with great caution.
