title: [Pseudoachalasia due to amyloidosis treated by botulinum toxin].
abstract: BACKGROUND
  Pseudoachalasia mimics primary achalasia and can provoke serious complications in the elderly.
  
  
  METHODS
  A 84 years-old woman had dysphagia with recurrent pneumonia. Pseudoachalasia related to a multifocal primitive amyloidosis was diagnosed. Treatment with botulinum toxin injection during a gastric fibroscopy resulted in clinical improvement, still notable 15 months later.
  
  
  CONCLUSIONS
  Botulinum toxin injection may be a useful tool in treatment of pseudoachalasia due to amyloidosis.
