Newborn With 21 Trysomy and Chilous pleural Effusion

Neonatal chylothorax results from the accumulation of chyle in the pleural space and may be either congenital or an acquired condition. Congenital chylothorax is most likely due to abnormal development or obstruction of the lymphatic system and often associated with hydropsfetalis. It can be idiopathic or may be associated with various chromosomal and other genetic abnormalities. It is important to identify infants with chylothorax, as there are specific issues that need to be addressed in the management of these patients. In the neonate, chylous effusion is a common cause of pleural effusions and characterized as an exudate because of the high protein and lipid content once the infant is fed. The fluid will be clear/yellow to slightly cloudy in the unfed state and will quickly become milky following feeding, as chylomicrons appear in the fluid. Lymphocytes predominate in the differential cell count of chyle. The volume of fluid output can be high, and management can be challenging. We present a case of newborn with 21 trisomy who developed moderate RDS, chest X-ray and US reveal pleural effusion on right side, rapid intervention was made before deterioration, requiring intensive life-saving measures. We review the common manifestations of congenital chylotoraxes and emphasize the importance of early diagnosis and intervention in preventing devastating outcomes from this condition.
