Chylothorax in Down's syndrome associated with hydrops fetalis
The Journal of the Singapore Paediatric Society
|January 1, 1989
Summary
Hydrops fetalis can mask Down syndrome symptoms in newborns due to severe swelling. Consider Down syndrome in fetuses or infants with fluid buildup, like pleural effusion or ascites.
Area of Science:
- Perinatology
- Medical Genetics
Background:
- Hydrops fetalis, a condition of abnormal fluid accumulation in fetuses, is rarely associated with Down syndrome.
- Diagnosing Down syndrome in neonates with hydrops fetalis presents significant challenges due to obscured clinical features.
Observation:
- Severe edema in hydropic newborns can mask the typical physical signs of Down syndrome.
- Affected infants may be critically ill at birth, limiting the time for diagnostic investigations.
Findings:
- Down syndrome should be a consideration in the differential diagnosis of fetuses and neonates presenting with hydrops fetalis.
- The presence of pleural effusion and/or ascites in neonates warrants consideration for underlying Down syndrome, even with hydrops fetalis.
Implications:
- Early consideration of Down syndrome in hydropic neonates may facilitate timely diagnosis and management.
- Recognizing this association can improve diagnostic yield in cases of unexplained hydrops fetalis.
