Bronchopneumonia

Overview


Plain-Language Overview

Bronchopneumonia is an infection that affects the lungs, specifically targeting the small airways called bronchi and the surrounding lung tissue. It causes inflammation and fluid buildup, which can make breathing difficult and lead to symptoms like cough, fever, and chest pain. This condition primarily involves the respiratory system and can impair oxygen exchange, leading to shortness of breath and fatigue. It often develops after a cold or flu, especially in people with weakened immune systems or chronic lung diseases. The infection can be caused by various bacteria, viruses, or fungi, making it important to identify the cause for proper treatment.

Clinical Definition

Bronchopneumonia is a type of pneumonia characterized by patchy, multifocal inflammation centered around the bronchi and bronchioles, extending into the adjacent alveoli. It is commonly caused by bacterial pathogens such as Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenzae, often following viral upper respiratory infections or aspiration. The core pathology involves bronchial inflammation, alveolar exudate, and consolidation in multiple lobules, distinguishing it from lobar pneumonia which affects a whole lobe. Clinically, it presents with fever, productive cough, dyspnea, and sometimes pleuritic chest pain. It is significant due to its potential to cause respiratory failure, sepsis, and lung abscesses if untreated. Diagnosis and management require prompt recognition to reduce morbidity and mortality.
