title: Saccular cyst with atypical presentation.
abstract: Respiratory obstruction and stridor in infants and children are not uncommon. A rare cause of these sometimes life-threatening symptoms is the congenital saccular cyst.
  
  
  OBJECTIVE
  We present the case of a 5-year-old girl with a cervical tumor, which appeared after a laryngeal endoscopic surgery of a saccular cyst with two relapses and a particular local evolution of its recurrence through the cricothyroid membrane.
  
  
  METHODS
  The patient data has been reviewed over the entire follow-up period and a thorough an analysis of her investigations and surgery was performed.
  
  
  RESULTS
  The unusual evolution of this case was marked by an atypical exteriorization - not found in the published literature. The surgical approach was external, by paramedian thyrotomy, with no further long-term recurrence.
  
  
  CONCLUSIONS
  An accurate diagnosis of saccular cysts can be made with the help of medical history, by an endoscopic visualization of the lesion and by the CT-scan imaging of the cervical region. Sometimes, saccular cysts can extend beyond laryngeal limits, determining fluid-filled tumors in the cervical region.
