Match each neonatal respiratory condition with its classic clinical presentation and chest radiograph findings.

  • Respiratory distress syndrome (RDS)Premature infant; radiograph reveals diffuse, fine reticulogranular (ground-glass) opacities and prominent air bronchograms.
  • Transient tachypnea of the newborn (TTN)Term infant delivered via cesarean section; radiograph shows prominent perihilar streaking and fluid in interlobar fissures.
  • Meconium aspiration syndrome (MAS)Post-term infant; radiograph shows asymmetric, coarse, patchy infiltrates with significant lung hyperinflation.
  • Congenital diaphragmatic hernia (CDH)Infant with a scaphoid abdomen; radiograph demonstrates air-filled loops of bowel in the left hemithorax and mediastinal shift.

Cevap

Respiratory distress syndrome matches with premature infant and ground-glass opacities. Transient tachypnea of the newborn matches with cesarean delivery and fluid in the interlobar fissures. Meconium aspiration syndrome matches with post-term infant and patchy infiltrates with hyperinflation. Congenital diaphragmatic hernia matches with scaphoid abdomen and bowel loops in the chest.
Each neonatal respiratory condition presents with distinct clinical and radiographic hallmarks directly tied to its underlying pathophysiology. RDS is defined by surfactant deficiency in preemies (ground-glass opacities). TTN is delayed fluid clearance common in C-sections (fluid in fissures). MAS involves meconium aspiration in post-term infants (patchy infiltrates, hyperinflation). CDH involves anatomical herniation of the bowel (scaphoid abdomen, bowel loops in chest).

Adım Adım Çözüm

1
Analyze the description of the premature infant with ground-glass opacities.
Matches Respiratory distress syndrome (RDS).
Prematurity and ground-glass opacities (due to diffuse microatelectasis) are the hallmark signs of surfactant deficiency.
2
Analyze the description of the term infant born via cesarean section with perihilar streaking.
Matches Transient tachypnea of the newborn (TTN).
Lack of vaginal squeeze during C-section delays fetal lung fluid clearance, leading to fluid visible in the fissures.
3
Analyze the description of the post-term infant with coarse infiltrates and hyperinflation.
Matches Meconium aspiration syndrome (MAS).
Post-term infants are at high risk for passing meconium; the ball-valve obstruction causes hyperinflation and patchy pneumonitis.
4
Analyze the description of the infant with a scaphoid abdomen and bowel loops in the chest.
Matches Congenital diaphragmatic hernia (CDH).
A scaphoid abdomen occurs because abdominal organs have herniated into the thoracic cavity, visibly displacing the mediastinum.
