Presentation
Presented with chronic cough, worsened in the last 6 months.
Patient Data
There is a diffuse bronchointerstitial pattern throughout the lungs. The bronchial walls are asymmetrically thickened and visible well out into the periphery. The bronchi do not taper well which may indicate bronchiectasis. Multiple lobar bronchi are visualized with thickened walls. The end-on bronchi form doughnuts, or cygnet rings. There is also a focus of increased interstitial pattern at the tip of the bronchus to the right cranial lung lobe.
Case Discussion
The bronchoscopic exam revealed copious amounts of mucus within the airways. A bronchioalveolar lavage showed increased numbers of eosinophils and neutrophils supporting a diagnosis of eosinophilic bronchopneumopathy. No organisms were cultured from the BAL.
Differential diagnoses could include other causes of chronic bronchitis.
