OBJECTIVE: To study the pathology, imaging and clinical features of a child with trisomy 21 syndrome associated interstitial lung disease.
METHOD: Data of a case with trisomy 21 syndrome associated interstitial lung disease confirmed by lung imaging and pathology were collected, analyzed and the related reports in literature were reviewed.
RESULT: The patient was a one year and 7 months old boy who suffered from severe pneumonia and recurrent infection during his hospital stay. When his disease was stable, he did not have shortness of breath and cyanosis, but a chest computed tomography (CT) showed ground-glass opacity, regional emphysema, band-like change in lung parenchyma, which indicated interstitial lung diseases. Unequal air inflation in bilateral lungs and diffuse over-distension of peripheral air spaces in lung surface were seen through thoracoscope. Pathological examination indicated that alveolar, alveolar ducts and alveolar sac were enlarged, alveolar septa was expanded. There were two reports in lung pathology of trisomy 21 syndrome, alveolar growth abnormalities was seen in 86%-88% cases. The multiple subpleural cysts in chest CT was characteristic. Clinically, trisomy 21 syndrome had high morbidity of respiratory tract infection and progress to respiratory failure frequently. Prolonged postoperative desaturation was constant which required long duration of respiratory support.
CONCLUSION: Trisomy 21 syndrome associated alveolar growth abnormalities were confirmed, which manifest as alveolar simplification in pathology and interstitial lung diseases in imaging. The risk of respiratory failure in these cases caused by infection and surgery should be considered.
