• RF
• There is a mild diffuse interstitial lung pattern
  that is consistent with normal aging.
• A large mass of soft tissue opacity is present in
  the right caudal lung lobe.
• RD
• Solitary pulmonary mass left caudal lung lobe
• R/O
• Primary pulmonary tumor

6
2-year old cat Smokey

• Hx Presented for her annual PE and vaccinations.
  The PE is normal but during your conversation
  with the owners they mention that she
  occasionally coughs and gags, sometimes vomiting
  a hairball.

2-year old cat Smokey

• RF
• Cardiovascular structures and pulmonary
  parenchyma are normal.
• In the lateral view there is a mild increase in
  opacity in the lungs cranial to the heart. This
  is the result of superimposition of the forelimb
  musculature over the thorax.
• RD
• Normal thorax

2-year old German Shepherd

• RF
• There is a striking pulmonary infiltrate present
  which is predominately surrounding the airways,
  making them appear thick.
• There is a peribronchial infiltrate.
• RD
• Broncho-interstitial pulmonary pattern with
  bronchial pattern being primary
• R/O
• Allergic lung disease
• Parasitic lung disease
• PIE
• Bronchitis

• RF
• Multiple soft tissue nodules of varying size and
  shape were noted scattered throughout the lung
  fields.
• There is an increase in cranio-caudal width of
  the heart and an increase in sternal contact on
  the lateral view.
• The trachea appears to be elevated and the heart
  appears elongated.
• There appears to be some bulging in the area of
  the left atrium.
• The DV view suggests rounding of the heart with a
  slight deviation to the left side.
• RD
• Cardiomegaly
• Multiple soft tissue pulmonary nodules r/o
  Pulmonary metastatic disease
• R/O
• Primary cardiac disease
• Active pericardial effusion ( Radiographs taken
  the day before showed a much smaller heart)
• Hemangiosarcoma involving the right atrium
• Ectopic thyroid tumor
• Next
• Cardiac ultrasound

1.5 year old German Shepherd

• RF
• The cardiovascular structures are within normal
  limits.
• The pulmonary vessels are within normal limits.
• A prominent skin-fold is noted in the right
  hemi-thorax and may be mistaken for pneumothorax.
• The extra-thoracic structures are within normal
  limits.
• RD
• Normal thorax

• RF
• Severe, diffuse (coarsely) nodular interstitial
  infiltrate.
• A focal, irregular soft tissue opacity is noted
  over the cranioventral heart border on the
  lateral view, localized to the left cranial lung
  on the VD view.
• Pleural fissure lines are present.
• RD
• Poorly circumscribed left cranial lobe mass and
  diffuse severe coarsely nodular interstitial
  infiltrate
• R/O
• Neoplasia
• Fungal disese

• RF
• Severe infiltrate involving the lung field.
• Heavy interstitial to alveolar infiltrate.
• Loss of vessel clarity.
• Enlarged cardiac silhouette. Increased width of
  the heart, especially in the area of the right
  ventricle.
• Air lucency between the right lung, which is
  retracted from the chest wall.
• Visualization of the aorta and esophagus
  indicative of pneumomediatinum.
• RD
• Severe diffuse pulmonary infiltrate and enlarged
  right ventricle
• Mild pneumothorax
• R/O
• Cor pulmonale
