-month-old girl was referred to our hospital due to a bout of sneezing,
mucoid discharge, and progressive dyspnea for 2 days. The infant was
born at 38 weeks by vaginal delivery at a weight of 3,110
g. No respiratory disorders were reported during the neonatal
period. During her first 5 months of life, the patient was fed by
bottle, had proper weight gain, and remained asymptomatic. There
was no family history of congenital defect or consanguinity.
A physical examination revealed a well-nourished girl. She presented
subcostal and intercostal retractions with no cyanosis. Breath sounds
were diminished on the right side, and cardiac sounds were displaced to
that side with no murmur. Vital signs were normal, including oxygen
saturation levels. The results of serum chemistry tests and CBC count
also were normal.
