4. The thoracic CT shows left lower lobe consolidation with central cavitation
The thoracic CT shows left lower lobe consolidation and ground-glass opacity, with some volume loss evidenced by posterior retraction of the left major fissure, but the left lower lobe airways are clearly patent- no endobronchial obstruction is present. Cavitation is present within the densest area of consolidation within the left lower lobe opacity. While diaphragmatic hernias can occasionally simulate the presence of a left base pneumonia or even a left base mass, no significant diaphragmatic hernia is present. No pleural effusion, loculated or otherwise, is seen. There is focal consolidation in the left base [note the air bronchograms], but no discrete mass is present.
The patient’s cough persisted, relatively unchanged.
