Pulmonary cavitation.

All true

Upper lobe cavitating pneumonia is classical of pulmonary tuberculosis.

Klebsiella and Staph. aureus may cause acute cavitating pneumonia. Strep. pneumoniae does so occasionally.

Paragonimus westermani (the lung fluke) causes pulmonary cavitation but the cavities are only about 1cm across and sometimes are only recognised as such on CT scanning.
