title: Caudal cingulate infarction manifesting astasia.
abstract: BACKGROUND
  Astasia is a rare presenting symptom of stroke, usually known as 'thalamic astasia', induced by a lesion in the ventrolateral thalamus. We report a case of caudal cingulate infarction manifesting astasia.
  
  
  METHODS
  A 58-year-old male presented with inability to sit, stand and walk (astasia). No apparent motor weakness was noticed in the extremities. MRI revealed cerebral infarction in the caudal cingulate gyrus, which was located between the vertical commissure anterior (VCA) line and vertical commissure posterior (VPC) line. His symptoms persisted for 1 year to a lesser degree.
  
  
  CONCLUSIONS
  Lesions in the caudal cingulate gyrus can present with astasia. The responsible lesion is located in the cingulate gyrus between the VCA and VPC line, which might correspond to the caudal cingulate zone in humans. We should keep in mind that astasia can be a presenting symptom of stroke.
