Overview

Aspiration pneumonia is caused by inhalation of secretions, gastric contents or any foreign material which reaches lung paraenchyma and damages lung tissueby inflammation

Causes

Life-threatening Causes

• Life-threatening causes of aspiration pneumonia include:
  • Stroke
  • Unconsciousness
  • Brain stem palsy

Common Causes

Aspiration pneumonia may be caused by:

• Breathing in different particles such as:
  • Food
  • Saliva
  • Liquids
  • Vomit

Less Common Causes

Less common causes of aspiration pneumonia include:

• Inhalation of:
  • Foreign body
  • Meconium
  • Oil

Genetic Causes

• There are no genetic causes of aspiration pneumonia.
• However, patients with paralysis of lower cranial nerves (paired 9th (glossopharyngeal), 10th (vagal), 11th(accessory) and 12th (hypoglossal)) due to syndromes are prone to aspiration syndromes. They may include:
  • Cerebral parlay
  • Amyotrophic lateral sclerosis (ALS)
  • Spinal muscular atrophy
  • Bulbospinal muscular atrophy (BSMA)
  • Unclassified MNDs (Sandhoff disease, triple-A-syndrome, Brown-Vialetto-Van Lare-syndrome)
  • Hereditary neuropathy
