Alveolar

lung pattern

Cranio-ventral

Aspiration pneumonia
Lung lobe torsion
(generally: left cranial lunge lobe, right middle lung lobe)
Bronchopneumonia

Caudo-dorsal

Non-cardiogenic pulmonary oedema

  • Neurogenic (e.g. postictal, electro caution/electrocution, head trauma)
  • Asphyxia (e.g. Brachycephalic syndrome, strangulation, laryngeal paralysis)
  • Hypoalbuminaemia
  • Immune-mediated diseases
  • Near drowning
  • Smoke inhalation
  • Inhaled toxins
  • Anaphylaxis
  • Multisystemic – inflammatory and non-inflammatory disease
    (e.g. uremia, sepsis, acute pancreatitis)

Neoplasia
(bronchogenic carcinoma may affect more than one lung lobe; histiocytic sarcoma)

Inhaled foreign body
(grass awn, often no radiographic abnormalities)

Perihilar

Cardiogenic pulmonary oedema (dog)

Peripheral

Pulmonary infarcts
(lung) worms
(Angiostrongylus vasorum; Crenosoma vulpis (additional bronchial lung pattern))

Diffuse

Acute respiratory distress syndrome (ARDS)
Haemorrhage (DIC, trauma)
Atelectasis
Cardiogenic oedema (cat)
