title: Cervical bronchogenic cyst mimicking thyroglossal cyst: case report and literature review.
abstract: BACKGROUND
  Bronchogenic cysts are rare congenital malformations of ventral foregut development, often with an intrathoracic location. Presentation at the cervical region is very rare.
  
  
  METHODS
  We present the case of a 29-year-old female who demonstrated a 3-cm medial neck mass in relation to the hyoid cartilage. The mass was painless with a rubbery consistency, moving with tongue movements. Cervical ultrasonography and thyroid scan were suggestive of nonfunctioning thyroglossal cyst. Histopathological examination revealed the presence of a cervical bronchogenic cyst.
  
  
  CONCLUSIONS
  Cervical bronchogenic cyst is a rare congenital malformation that usually appears as a painless neck mass. Imaging findings are not specific for differentiating thyroid, thyroglossal, branchial or thymus cyst; therefore, clinical observation of an asymptomatic lateral neck mass in an adult should include the possibility of a bronchogenic cyst in the differential diagnosis.
