Classification

Based on duration

  • Acute : If symptoms are present for less than 6 weeks before presenting to medical care.[1]
  • Chronic : If symptoms persist for more than 6 weeks

Based on Etiology

Primary When Abscess develops among patients who were healthy previously or with high risk factors such as those prone for aspiration

  • Aspiration of oropharyngeal secretions
  • Immunodeficiency conditions like HIV
  • Necrotizing pneumonitis

Secondary When abscess develops among patients with an underlying lung abnormality

  • Bronchial obstruction
  • Hematogenic dissemination
  • Infection spread from mediastinum
  • Coexisting Lung Diseases

Based on mode of spread

Bronchiogenic

  • Aspiration of Oropharyngeal secretions
  • Bronchial obstruction by Tumor
  • Foreign body, Congenital Malformations and Enlarged LymphNodes

Hematogenic

  • Infective endocarditis
  • Abdominal Sepsis
  • Septic Thromboembolism

Risk Factors

Common risk factors in the development of lung abscess are

Common Risk Factors

  • Alcoholism
  • Seizer disorder
  • Artificial ventilation
  • Coma
  • Neuromuscular disorders with bulbar dysfunction
  • Nocturnal Aspiration /Inability to cough
  • Bronchial obstruction
  • Gingivo-dental sepsis
  • Diabetes Mellitus
  • Immunosuppression

Less Common Risk factors

  • Drug abuse
  • Malnutrition
  • Mental retardation
  • Gastroesophageal reflux disease
