title: Recurrent isolated oculomotor nerve palsy after radiation of a mesencephalic metastasis. Case report and mini review.
abstract: BACKGROUND
  Recurrent oculomotor nerve palsies are extremely rare clinical conditions.
  
  
  METHODS
  Here, we report on a unique case of a short-lasting recurrent unilateral incomplete external and complete internal oculomotor nerve palsy. The episodic palsies were probably caused by an ipsilateral mesencephalic metastasis of a breast carcinoma and occurred after successful brain radiation therapy.
  
  
  CONCLUSIONS
  While the pathogenic mechanism remains unclear, the recurrent sudden onset and disappearance of the palsies and their decreasing frequency after antiepileptic treatment suggest the occurrence of epilepsy-like brainstem seizures. A review of case reports of spontaneous reversible oculomotor nerve palsies is presented.
