title: Occlusion of the external cervical os after conization in a postpuerperal amenorrheic woman.
abstract: BACKGROUND
  Complete occlusion of the cervical canal following conization is an uncommon complication.
  
  
  METHODS
  We encountered a case in a woman with lactation amenorrhea who after conization to treat cervical intraepithelial neoplasia (CIN) 3 developed hematometra and did not resume menstruation. This case was diagnosed early by ultrasonic tomography and magnetic resonance imaging (MRI).
  
  
  CONCLUSIONS
  Postpuerperal amenorrheic women should be managed with care because of the increased risk of occlusion of the cervical duct after conization.
