• RF
• The bronchi are noted to be calcified.
• The mineralized bronchi are seen as linear
  structures overlying the heart.
• Mineralized end-on bronchi are also visible.
• There is an area of increased interstitial
  opacity beneath the caudal vena cava.
• Multiple small round calcified structures are
  noted in the periphery of the lungs.
• These are pulmonary osteomas or pneumoliths
  islands of mineralization within the lung
  parenchyma of unknown etiology. They are an
  incidental finding and should not be mistaken for
  metastatic disease.
• There is an incidental finding of a small amount
  of gas in the esophagus cranial to the heart.
• RD
• Bronchial lung pattern
• Interstitial opacity in the accessory lung lobe
• R/O
• Chronic bronchitis
• Cause may be allergic or inflammatory or possibly
  an inhaled toxin
• Parasitic

  coughing are also reported.

9-year old HimalayanBlue

• RF
• Incidental finding of generalized skeletal
  osteopenia.
• There is a diffuse increase in pulmonary opacity
  with a faint nodular pattern visible.
• In the lateral view there are patchy pulmonary
  infiltrates partially obscuring the cardiac
  border.
• In the VD biew there is a focus of increased
  opacity in the region of the right middle lung
  lobe. An air bronchogram is visible in this area.
• The lateral radiograph of the cervical region
  shows a marked stenosis of the trachea in the
  region of the tracheal cartilages.
• RD
• Diffuse broncho-interstitial pattern with focal
  alveolar changes
• Tracheal stenosis
• R/O
• Feline asthma
• Pneumonia

12-year old MN Springer Spaniel Rocky

• RF
• In the lateral view the cardiac silhouette
  appears round and there is no visible cardiac
  apex. This appearance of the heart is typical of
  that seen in a left lateral recumbent view.
• In the VD view the left margin of the heart is
  unusual in shape. This is the result of rotation
  of the patient to the right and projection of the
  aorta beyond the margin of the heart.
• There is a significant bronchial pattern present.
• Bronchial calcification is present extending over
  the heart and into the caudodorsal lung fields.
• The tracheal cartilages are mineralized
• RD
• Bronchial and tracheal calcification
• Bronchial pattern
• R/O
• Incidental feeding related to normal aging
  changes
• Bronchopneumonia in the past and bronchial
  mineralization is a permanent residual change

4-year old DSHJane

• Hx Presented for evaluation of abdominal
  distension and increased liver enzyme values. She
  also has bilateral retinal detachment.

4-year old DSHJane

• RF
• There is a diffuse interstitial lung pattern
  present.
• There is areas of peribronchial distribution of
  the interstitial infiltrate are appreciated.
• In the VD view there is tenting of the diaphragm
  and in the lateral view the diaphragm is flatter
  than normal.
• Liver extends beyond the costal arch
• RD
• Diffuse pulmonary pattern
• Thoracic hyperexpansion
• Hepatomegaly or could be due to pulmonary
  hyperinflation
• R/O
• Feline airway disease (Asthma)

15
6-year old Siamese catCaesar

• Hx Presented for chronic vomiting. Abdominal
  radiographs were obtained to evaluate for the
  cause of vomiting.

16
6-year old Siamese catCaesar

• RF
• There is a diffuse nodular interstitial lung
  pattern.
• There is bronchial thickening and peribronchial
  cuffing.
• A small area of mineral opacity is noted dorsal
  to the heart at the 7th intercostal space.
• There is increased distance between the heart and
  the diaphragm and the diaphragm is flattened.
• A large round structure containing granular
  material and with a mineral opacity margin is
  noted in the cranial abdomen. This is the
  stomach.
• RD
• Diffuse nodular interstitial lung pattern with
  occasional bronchial markings and peribronchial
  cuffing
• Thoracic hyperexpansion
• R/O
• Chronic/severe feline asthma

6-year old Cock-a-Poo Missy

• RF
• Increased opacity and air-bronchograms are
  present in the region of the right cranial, right
  middle lung lobe and the cranial portion of the
  right caudal lung lobe.
• There is slight retraction of the right cranial
  lung lobe and two faint pleural fissure lines are
  seen.
• The heart is shifted slightly to the right.
• In the Vd view there is increased thickness of
  the soft tissues along the right lateral thoracic
  wall.
• A rounded soft tissue opacity structure is seen
  on the right side at the 6th intercostal space
  and cranial to the stomach. The clear margins of
  this structure indicate that it is surrounded by
  air and therefore on the outer surface of the
  animal, may be enlarged mammary glands.
• In the lateral view there is a mineral opacity
  structure in the dorsal thorax at the 8th
  intercostal space.
• There are fractures of the 8th to 13th ribs on
  the left side.
• RD
• Alveolar pattern of the right cranial, right
  middle and right caudal lung lobes due to
  pulmonary contusions
• Mild cardiac shift
• Fractured left 8th through 13th ribs
• Swelling of the right lateral thoracic wall

  mitral murmur and pulmonary crackles. These
  radiographs were obtained in January.

12-year old Cocker SpanielFeetie

• RF
• There is increased length of the caudal border of
  the heart and elevation of the mainstem bronchi.
• There is mild widening of the heart in the
  lateral view and an increase in sternal contact.
• The pulmonary vessels are slightly small (the dog
  is currently on Lasix)
• There is a moderate diffuse increase in pulmonary
  opacity and bronchial markings are prominent.
• The cranial mediastinum is 2x the width of the
  vertebral bodies on the DV view. This is the
  result of fat deposition.
• RD
• Moderate generalized cardiomegaly
• Left-sided enlargement predominates
• Diffuse bronchointerstitial lung pattern
• R/O
• Mitral valve endocardiosis and insufficiency
• Incidental pulmonary changes due to normal aging
  process
• Cardiogenic interstitial pulmonary edema
