Presentation
Known Down syndrome and complete AV septal defect verified by echocardiography. Fever, reduced blood oxygen saturation, tachy-dyspnea.
Patient Data
Marked cardiomegaly as a consequence of the complete AV septal defect.
Bilateral irregular, partially confluous, diffuse haziness showing a perihilar and right-sided predominance.
Partial effacement of the diaphragm contours.
Presence of air bronchograms.
Case Discussion
The observed marked cardiomegaly and perihilar (bat wing) opacities are in line with cardiogenic lung edema, as a sequela of the complete AV septal defect.
Considering the clinical picture the more confluous areas of consolidations also raise the possibility of superimposed pneumonia.
