Presentation
Premature newborn (born at 25 weeks) on high frequency jet ventilation.
Patient Data
Series of chest and abdominal radiographs:
First one obtained after ET tube placement, central lines and administration of a dose of surfactant.
10 hrs image:
Lungs are more expanded than prior image. Multiple patchy opacities scattered throughout left lung and right perihilar region with non-branching linear radiolucencies more prominent in the left lung.
Tubes and lines are in satisfactory positions.
Numerous diffuse bubbly and linear radiolucencies occupying most of the left lung field. Similar radiolucencies, but less extensive, also seen in the right perihilar region and right upper lobe.
Findings are consistent with pulmonary interstitial emphysema.
Similar findings to before:
Tubes and lines are in a satisfactory positions.
Case Discussion
This is a typical case of pulmonary interstitial emphysema (PIE) in a premature newborn who is on mechanical ventilation to treat surfactant deficiency. It developed in the first day of life and significantly improved by the 36 hrs image.
