title: [Incomplete Horner's syndrome as a presenting sign of fourth ventricle ependymoma].
abstract: METHODS
  The case of 44 year old male patient with palpebral ptosis and trigeminal neuralgia as presenting sign of fourth ventricle ependymoma is reported. After surgical treatment, the patient developed a residual paresis of the sixth cranial nerve.
  
  
  CONCLUSIONS
  Horner's syndrome occurs due to an alteration of the sympathetic innervations of the eye and adnexa. Some tumours may be the cause, in our case an ependymoma of the fourth ventricle, which onset exceptionally with blepharoptosis and involvement of the ophthalmic division of trigeminal nerve, due to the proximity of these nerve fibres at the brainstem.
