Anaerobic lung abscess

An anaerobic lung abscess is a localized, cavitary pulmonary infection characterized by microbial liquefactive necrosis of the lung parenchyma, driven predominantly by anaerobic oral commensals such as *Peptostreptococcus*, *Fusobacterium*, and *Prevotella* species This condition most frequently arises in adult populations predisposed to microaspiration of oropharyngeal secretions, particularly individuals with severe periodontal disease, impaired cough reflexes, dysphagia, or altered consciousn...

Pathophysiologically, the aspirated anaerobes incite intense focal pneumonitis and tissue destruction, progressing over days to weeks into a thick-walled necrotic cavity that classically demonstrates an air-fluid level on thoracic imaging and produces putrid, foul-smelling sputum
