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
