Honeycombing refers to the computed tomographic (CT) manifestation of diffuse pulmonary fibrosis (usual interstitial pneumonia). The Fleischner Society definition is clustered cystic air spaces (between 3-10 mm in diameter but occasionally as large as 2.5 cm) which are usually subpleural and bas...
Pectus excavatum (or funnel chest) is a congenital chest wall deformity characterised by concave depression of the sternum, resulting in cosmetic and radiographic alterations. Epidemiology It is the most common chest wall deformity, accounting for approximately 90%, and occurs in up to 1 in 30...

Coal workers' pneumoconiosis
Coal workers' pneumoconiosis (CWP) is an occupational disease (type of pneumoconiosis) caused by exposure to coal dust free of silica (washed coal). Histologically, CWP is classified according to disease severity into simple (presence of coal macules) and complicated (with progressive massive fi...
Monod sign (lungs)
Monod sign (often spelt Monad sign) simply describes air that surrounds a mycetoma (most commonly an aspergilloma) in a pre-existing pulmonary cavity 1-3. It should not be confused with the air crescent sign which is seen in recovering angioinvasive aspergillosis 4. The air crescent sign herald...
Silzbach sarcoidosis chest radiographic staging system
Silzbach system is a chest radiographic staging method for sarcoidosis. stage 0: normal chest radigraph: 10% at time of diagnosis stage I: lymph node enlargement: 50% at time of diagnosis stage II: lymph node enlargement and pulmonary opacities: 30% at time of diagnosis stage III: pulmonary ...
Non small cell lung cancer (staging) - 7th edition
Non-small cell lung cancer (NSCLC) staging can be accomplished both by the TNM system or by the AJCC staging system. This staging has since been revised. See IASLC 8th edition staging. For a general discussion of these tumours please refer to the article on non-small cell lung cancer (NSCLC). ...
Acute unilateral airspace opacification (differential)
Acute unilateral airspace opacification is a subset of the differential diagnosis for airspace opacification. Differential diagnosis The exhaustive list of all possible causes would be huge, but a useful framework includes : pus, i.e. infection bacterial pneumonia fungal pneumonia viral ...
Acute airspace opacification with lymphadenopathy (differential)
Acute airspace opacification with lymphadenopathy is a subset of the differential diagnosis for generalised airspace opacification and includes: post-obstructive causes (usually chronic, but 'new' changes can occur) primary lung cancer pulmonary metastases lymphoma/leukaemia infection pri...
Air bronchogram refers to the phenomenon of air-filled bronchi (dark) being made visible by the opacification of surrounding alveoli (grey/white). It is almost always caused by a pathologic airspace/alveolar process, in which something other than air fills the alveoli. Air bronchograms will not ...
Caplan syndrome, also known as rheumatoid pneumoconiosis, is the combination of seropositive rheumatoid arthritis and a characteristic pattern of fibrosis. Although first described in coal miners (coal workers' pneumoconiosis), it has subsequently been found in patients with a variety of pneumo...
The Carney triad (not to be confused with the related Carney Stratakis syndrome, or the unrelated Carney complex) is a rare syndrome defined by the coexistence of three tumours: extra-adrenal paraganglioma (e.g. spinal paraganglioma) initially, only functioning extra-adrenal paragangliomas wer...
Water-lily sign (liver)
The water-lily sign is seen in hydatid infections when there is detachment of the endocyst membrane which results in floating membranes within the pericyst that mimic the appearance of a water lily. It is classically described on plain radiographs (mainly chest X-ray) when the collapsed membran...
Air crescent sign (lung)
An air crescent sign describes the crescent of air that can be seen in invasive aspergillosis, semi-invasive aspergillosis or other processes that cause pulmonary necrosis. It usually heralds recovery and is the result of increased granulocyte activity. In angioinvasive fungal infection, the no...
Eosinophilic lung disease
Eosinophilic lung diseases are heterogenous group of disorders that are characterised by excess infiltration of the eosinophils within the lung interstitium and alveoli and are broadly divided into three main groups 1: idiopathic: unknown causes secondary: known causes eosinophilic vasculitis...
Chronic bilateral airspace opacification (differential)
Chronic bilateral airspace opacification is a subset of the differential diagnosis for airspace opacification. An exhaustive list of all possible causes of chronic bilateral airspace opacities is long, but a useful framework is as follows: inflammatory sarcoidosis Wegener's granulomatosis eo...
Cystic fibrosis (CF) is an autosomal recessive genetic disease that affects the exocrine function of the lungs, liver, pancreas and small bowel resulting in progressive disability and multi-system failure. This article is a general discussion of the disease. Each organ system will be discussed s...
