- Pneumococcal pneumonia produces consolidation in the right upper lobe with multiple air bronchograms (black branching structures) present since the spaces surrounding the air-filled bronchi normally contain air but now are filled with inflammatory exudate. There is no cavitation, the disease is in the lower lobe and it contains air bronchograms, all characteristics of pneumonia caused by Streptococcus Pneumoniae (formerly known as Diplococcus Pneumoniae)

- Branching, linear, tubular lucency representing a bronchus or bronchiole passing through airless lung parenchyma . This sign indicates that the underlying opacity must be parenchymal rather than pleural or mediastinal in location.
- air bronchogram - indicates a parenchymal process, including non-obstructive atelectasis, as distinguished from pleural or mediastinal processes
- mycetoma :ورم فطري
- Refers to the air surrounding a radio opaque material in a crescentric manner along both its inner and outer margins indicating cavitary disease Aspergilloma in an old TB cavity

- علامة هلال الهوا In radiology, the air crescent sign is a finding on chest radiograph and computed tomography that is crescenteric and radiolucent, due to a lung cavity that is filled with air and has a round radioopaque mass.[1] Classically, it is due to an aspergilloma, a form of aspergillosis, that occurs when the fungus Aspergillus grows in a cavity in the lung.[2]

- Aspergilloma in tuberculous cavity. Coronal reformation image better shows the intracavitary aspergilloma (asterisk) in the left upper lobe. Also noted is subpleural honeycombing in the lower lobes consistent with idiopathic pulmonary fibrosis. The patient was a 58-year-old man with previous tuberculosis and intracavitary aspergilloma.
