A 45-year-old man is seen in the clinic for evaluation of bronchiectasis. Chest CT of this patient shows bronchiectasis of the airway leading to the right lower lobe only. Review of previous chest plain radiograms shows that he has had recurrent pneumonia of the right lower lobe seven times in the last 3 years.
Which of the following disorders is the likely culprit?
A. Allergic bronchopulmonary aspergillosis
B. Endobronchial carcinoid tumor
C. Panhypogammaglobulinemia
D. Kartagener's syndrome
E. Mycoplasma infection

absolutely correct
The answer is B.
Bronchiectasis is an abnormal and permanent dilation of the airway resulting from a number of insults.
The most common cause is severe viral infection or bacterial pneumonia with subsequent airway
destruction. The most commonly associated organisms include Staphylococcus aureus, Klebsiella, and anaerobes.
Mycobacterium tuberculosis can cause bronchiectasis; similarly, Mycobacterium avium complex has been described as both causing bronchiectasis and colonizing already bronchiectatic airways. These diseases result in focal bronchiectasis.
Allergic bronchopulmonary aspergillosis is associated with central bronchiectasis from chronic airway inflammation and mucus inspissation.
Impaired host defense mechanisms such as cystic fibrosis, immunodeficiency such as with
panhypogammaglobulinemia and HIV, and ciliary dysfunction as in Kartagener's syndrome are associated with diffuse bronchiectasis.
Focal bronchiectasis is usually caused by other disorders that lead to localized airway obstruction, such as enlarged lymph nodes, carcinoid tumors, and endobronchial lung cancer.
