Endobronchial carcinoid

Case contributed by Dr Muthu Magesh

Presentation

Complains of hemoptysis since 6 years - 1 episode per day ~ 10 ml per episode. Cough, breathlessness and wheeze since 6 years

Patient Data

Age: 40 years
Gender: Male
X-ray

Suspicious atelectatic changes in the right mid zone.

No other significant abnormality.

CT

Well-defined endoluminal homogenously enhancing soft tissue density lesion in the right
main bronchus, cranially extending into the carina and laterally extending into the origin of
right upper lobe bronchus and inferiorly extending into bronchus intermedius
causing right upper lobe bronchial luminal compromise with adjacent lung changes in
the form of atelectatic strands and ground glass opacities involving the apical & anterior
segments of the right upper lobe.
 

Case Discussion

Histopathologically proven case of bronchial carcinoid

Radiological features

  • hilar or para hilar mass with or without bronchial obstruction 
  • endobronchial nodules
  • sometimes as peripheral nodules

Highly vascular tumor and can mimic pulmonary varix or pulmonary artery aneurysm

Associated with diffuse or punctuate calcification.

Our case shows an enhancing endobronchial nodule with extrabronchial component (iceberg lesion) no evidence of calcification and seen causing mild atelectatsis and post obstructive pneumonia. 

CT valuable tool to look for mediastinal extension and to reveal mucoid impaction

Other differential is a bronchial fibroepithelial polyp.
