Presentation
Patient presents with fever and cough.
Patient Data
Radiograph shows a branching tubular structre extends from the left hilum in the left upper lobe with adjacent area of increased attenuation.
Large zone of decreased attenuation is seen in left lower lobe
Tubular Y-shaped nonenhancing lesion in the apicoposterior segment of the left upper lobe, a finding consistent with mucus impaction of the S1-2 bronchus (bronchocele). Surrounding fibrotic changes. Decreased attenuation is seen around fibrotic changes, a finding indicative of associated air trapping. These CT features are diagnostic of bronchial atresia.
Large zone of decreased attenuation is seen in lateral basal segment of left lower lobe with dilated bronchus in central area with no connection to main bronchial tree. This finding is due to bronchial atresia and air trapping.
Case Discussion
CT features are diagnostic for bronchial atresia of apicoposterior left-upper-lobe and subsegmetal lateral basal left-low-lobe bronchi.
