Patsy’s Pulmonary Changes

6-year-old American Bulldog with left-sided, muffled lung sounds received thorax CT scan to determine the cause.

  • Pet Name, Age, & Breed: Patsy, 6-year-old American Bulldog
  • Reason for referral: Repeated surgeries for ventral abdominal masses and cutaneous hemangiosarcomas; pre-surgical exam revealed muffled lung sounds on the left side of the chest and radiographs suggested a collapsed lung.
  • Suspected diagnosis: Collapsed lung; possible underlying bronchial disease.
  • Results of study: CT scan showed chronic bronchitis with increased airway resistance possibly causing lobar collapse. Bronchi had irregular wall contour and non-uniform tapering with abrupt narrowing, followed by dilation in secondary and tertiary bronchi. Some bronchial walls were thickened. The caudal subsegment of the left cranial lung lobe was small and atelectatic with a triangular-shaped alveolar pattern and no aerated bronchi. Patchy patterns in the right cranial and middle lobes likely represented interstitial fibrosis and aspiration pneumonia. No pulmonary nodules, masses, or neoplasia detected.
  • Recommendations: Consider bronchoscopy for further evaluation and airway sampling.
  • Notes: Possible etiologies for aspiration include brachycephalic airway syndrome or ciliary dyskinesia, given bronchial changes.
