Necrotizing pneumonitis

Clinical Notes

History of transient tachypnea of the newborn.


DR – Bilateral right greater than left consolidations; no mediastinal shift.

CT- Biltateral peripheral pulmonary consolidations with heterogeneous attenuation; pleura difficult to assess.

US – Consolidated lung with rounded hypoechoic foci; minimal exudative pleural disease.

MRI – Multiple fluid signal areas within densely consolidated lung.


Given the patient’s age and history of respiratory distress at birth, this likely is a late manifestation of neonatal pneumonia. Neonatal pneumonia may be acquired as a congenital infection (e.g., TORCH), postamnionitis (premature rupture of membranes), or transnatal (e.g., group B beta hemolytic streptococcus, E. coli, enterococcus, chlamydia).
