KeyWords: Bronchus; bronchiectasis; dyspnea
Anatomy: Thorax
Chapter: Obstructive disease
ACR: 60.26

Clinical Presentation: Cough and copious sputumproduction.
Comment: CT has replaced bronchography in the diagnosis ofbronchiectasis.
Typical findings include tubular images with aclear centre, known as "tram line " and
"signet-ring" signs(difference in diameter between the dilated bronchus and theadjacent
pulmonary artery). The most common causes ofbronchiectasis include infections
(Tuberculosis, viral orbacterial), cystic fibrosis, alpha-1-antitrypsin deficiency,allergic
bronchopneumonic aspergillosis, Kartagenerís syndrome,agammaglobulinemia, and
conditions associated with connectivetissue diseases or inflammatory bowel diseases.
Description: The frontal and lateral chest X-rays show a sub-hilarperibronchial
thickening. Bronchial dilatation is suspected on thelateral chest X-ray. CT images show
multiple areas ofbronchiectasis combined with bronchial wall thickening.
Enlargedmediastinal and right hilar lymph nodes are present.
