How Klebsiella infection appears on chest X-ray
Imaging Findings :
Homogeneous parenchymal consolidation containing air bronchograms (simulates pneumococcal pneumonia). Primarily involves the right upper lobe. Typically induces a large inflammatory exudate, causing increased volume of the affected lobe and characteristic bulging of an adjacent interlobar fissure.See this figure below:
Most commonly develops in alcoholics and in elderly patients with chronic pulmonary disease. Unlike acute pneumococcal pneumonia, Klebsiella pneumonia causes frequent and rapid cavitation, and there is a much greater incidence of pleural effusion and empyema.
