A rare cause of cavitatory pneumonia.
Radiographic findings of thick walled cavities in the lungs are typically seen in mycobacterial infections, malignant lesions, fungal infections, pulmonary vasculitis or other inflammatory lesions of the lungs. Necrotizing infections of the lungs caused by gram negative bacteria (Klebsiella, Psudomonas, Legionella) and Staphylococcus aureus may also form cavities of varying thickness, with consolidation. Escherichia coli pneumonia causing pulmonary cavities is very rare and the few cases reported are of pneumatocele formation. Here we present an unusual case of Escherichia coli infection as a rare cause of bilateral cavitating necrotizing pneumoniae, in a 67 year old male with uncontrolled type 2 diabetes mellitus.
