8 year old male neutered Domestic Shorthair with 1 month of anorexia and weight loss. What is the primary problem?
There is a rounded soft tissue mass superimposed on the heart base on both lateral projections, causing ventral deviation of the carina. On the ventrodorsal and dorsoventral projections, there is a mediastinal shift to the left and atelectasis of the left lung lobes. The right lung lobes are hyperinflated. There is a moderate bronchial pattern throughout the lungs.
- Pulmonary mass causing bronchial obstruction and secondary volume loss in the left lung lobes (neoplasia, abscess, granuloma).
- Pulmonary abscess (Nocardia or Actinomyces)
- The mass was confirmed by ultrasound and a fine needle aspirate was obtained for cytology. No further treatment was pursued.
