Transient Tachypnea of Newborn

  • Etiology: delayed pulmonary fluid resorption due to lack of a vaginal squeeze in infants born via cesarian section or precipitous vaginal delivery
  • CXR: normal lung volumes and prominent fine interstitial markings with +/- pleural effusion which resolves in 1-2 days, initially it is radiographically indistinguishable from Group B Streptococcus pneumonia
