Ultrasound and MRI showing:
- expanded right upper lobe with increased echogenicity/intensity
- compressed with decreased echogenicity/intensity of the right lower lobe and probably the middle lobe
- mass effect with a leftward shift of the heart
- compressed with a reduced volume of the normal left lung.
These findings are suggestive of a congenital lobar overinflation.
On imaging, MRI is relatively superior to ultrasound to differentiate between congenital lobar overinflation from pulmonary sequestration and microcystic adenomatoid malformation 1.
