Pulmonary gangrene can be a complication of necrotizing pneumonia and often represents a final stage in a continuum of progressive devitalisation of pulmonary parenchyma and is characterized by sloughing of a pulmonary segment or lobe.
In most instances, it occurs as a complication of necrotizing bacterial pneumonia but rarely can occur in other infections such as Mycobacterium tuberculosis 3.
CT
Some publications suggest the evolution of a crescent or rim of air within homogeneous opacification as the feature that heralds the development of pulmonary gangrene 2. The development of a "mass within a cavity" is also a concerning feature 5.
Treatment and prognosis
Many patients may need to undergo surgical procedures to debride necrotic lung parenchyma 1. Dependent on the severity, surgical procedures include pneumonectomy, lobectomy, or limited resection 6.
