title: Reversible posterior leukoencephalopathy syndrome after lateral skull base surgery.
abstract: OBJECTIVE
  To describe the clinical course, diagnostic features and management of a case of reversible posterior leukoencephalopathy syndrome after a lateral cranial base removal.
  
  
  METHODS
  A 58-year-old male patient with an inconspicuous clinical history presented with a lethargic state without localized neurologic deficit in the postoperative period of a subtotal petrosectomy for an adenoid cystic carcinoma of the temporal bone.
  
  
  METHODS
  Cranial T2-weighted magnetic resonance imaging showed increased signal intensity in the occipital and cerebellar regions, centered at the cortical and subcortical white matter. Antihypertensive drugs, anticonvulsants, and antibiotics were administered. A complete resolution of the symptoms and radiologic findings were achieved within 1 to 2 weeks.
  
  
  RESULTS
  The clinical presentation, radiologic findings, and resolution of the clinical setting are consistent with a diagnosis of reversible posterior leukoencephalopathy syndrome.
  
  
  CONCLUSIONS
  To our knowledge, this is the first report of reversible posterior leukoencephalopathy syndrome after a lateral cranial base surgery.
