This article explores its pathophysiology, clinical manifestations, diagnostic methods, treatment approaches, and surgical interventions. A clinical case is also presented to illustrate the real-world challenges of managing lung abscesses . Lung abscesses are circumscribed collections of pus within the lungs. They are often complicated to manage and difficult to treat and, in some cases, maybe life-threatening. Epidemiology As a result of the widespread availability of antibiotics,...
