Abstract
Gangrenous lung abscess (LA) is a limited form of lung gangrene. Although its frequency has decreased dramatically in recent years, it occupies an important place in clinical practice. Delaying its diagnosis or incorrect treatment leads to a risk to the patient's life. Timely diagnostics and treatment reduce morbidity and mortality rates. А 68-year-old woman who underwent a right upper bilobectomy for a gangrenous LA is presented. The case is considered in the context of the prolonged therapeutic course and the need for surgical treatment.
