Radiological imaging of congenital abnormalities of the lower respiratory system.

Dr/ ABD ALLAH NAZEER. MD.

Tracheal diverticulum and trifurcation.

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.

Post-intubation stenosis:

Tracheomalacia.

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

Bronchial atresia in a neonate.

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).

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.

Right lung agenesis.

SCIMITAR SYNDROME.

Congenital lobar emphysema.

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

Pulmonary arteriovenous malformation.
