Background, We encountered a case of bronchial atresia presenting niveau. During its course, the fluid mucocele level gradually elevated. Case. A 24-year old woman was found to have a round mass shadow in the right lower lung field by chest X-ray in October 1999. She was admitted to our hospital for detailed examination. A diagnosis of bronchial atresia was made based on the chest X-ray film, chest CT film, bronchography film and bronchoscopy. Subsequently, chest X-ray films have been taken regularly, and we observed a niveau in the mucocele on a chest X-ray film in August 2002. During the course the air fluid level elevated. Conclusion. Although the mechanism was unclear, we supposed that the bronchial mucocele might have been drained from collateral airways, for example, via Kohn's pores or Lambert's canal, and then it's level might have elevated again by bronchial gland secretion.
