X-ray - Two months later
Frontal
X-RAY FINDINGS: Bilateral ill-defined reticulonodular markings, more prominent on the right, with obscuration of the right hemidiaphragm and heart border, positive air-bronchograms and hyperinflation of the left lower zone. No apparent atelectasis. The widened upper mediastinum on the right is most likely due to non-centric projection (see trachea and clavicles). Dilated small and large bowel loops.
CONCLUSION: Given the history of a preterm neonate with IRDS and consecutive prolonged oxygenation therapy and normal infection parameters (normal CRP and leucocyte count), the most likely diagnosis is bronchopulmonary dysplasia (BPD).
