1. Radiological imaging of congenital abnormalities
of the lower respiratory system.
Dr/ ABD ALLAH NAZEER. MD.

3. Tracheal diverticulum and trifurcation.

7. Newborn with type II tracheal
agenesis , Coronal reformatted
images show two right bronchi
and left bronchus arising near
the midline from esophagus. The
trachea is absent.

9. Post-intubation stenosis:

11. Tracheomalacia.

12. Tracheal trifurcation. Coronal minimal intensity
projection images (A) and virtual bronchoscopy
(B) images depict tracheal trifurcation and the
origin of the three bronchi, respectively.
Tracheal diverticulum with
accessory right upper lobe bronchus

17. Bronchial atresia in a neonate.

18. Bronchial atresia. Axial
image in the mediastinal
window (A) shows a fluid
attenuating lesion with a
thin wall in the right upper
lobe (long arrow). High
resolution computed
tomography lung window
(B) image at the same
level shows the presence
of hyperinflation of the
lung segment peripheral
to the lesion (short arrow).

19. Pulmonary hypoplasia with broncho-esophageal fistula. Axial image in
the lung window (A) shows collapse of the right lower lobe. Aspirated
barium (arrow) in the lower lobe was visualized in the axial image in the
mediastinal window (B); C: Barium examination, carried out prior to
computed tomography through an esophageal tube, depicts the origin
of the right lower lobe bronchus from the esophagus.

23. Right lung agenesis.

29. SCIMITAR SYNDROME.

33. Congenital lobar emphysema.

46. Bronchogenic cyst in a 3-year-old boy with cough.

48. Pulmonary arteriovenous malformation.
