Ans. A. Right bronchus Ref: Nelson Textbook of Pediatrics 20th/ed p2057Explanation# Bronchogenic cysts arise from abnormal budding of the tracheal diverticulum of the foregut before the 16th week of gestation and are originally lined with ciliated epithelium.# They are more commonly found on the right and near a midline structure (trachea, esophagus, carina), but peripheral lower lobe and perihilar intrapulmonary cysts are not infrequent. Cysts are rarely demonstrable at birth.
