title: Transient kyphotic deformity of the thoracolumbar junction resulting from a large abdominal cyst: a case report.
abstract: BACKGROUND
  Pronounced kyphosis of the thoracolumbar junction is a common orthopedic problem in adolescents and may require prolonged bracing therapy or correction spondylodesis.
  
  
  OBJECTIVE
  To describe a case where a kyphotic deformity was related to gynecological instead of spine pathology.
  
  
  METHODS
  Case report.
  
  
  METHODS
  A 17-year-old girl presented with a structural hyperkyphosis of the thoracolumbar spine and radiographic changes of the involved vertebral end plates.
  
  
  RESULTS
  The thoracolumbar hyperkyphosis appeared to have evolved from a massive intra-abdominal ovarian cyst. Endoscopic paracentesis of the cyst resulted in a complete regression of the hyperkyphosis.
  
  
  CONCLUSIONS
  A hyperkyphosis is not always related to spine pathology, and other potential causes must be excluded before bracing therapy is initiated.
