Honeycombing (lungs)
Honeycombing is a CT imaging descriptor referring to clustered cystic air spaces (between 3 and 10 mm in diameter, but occasionally as large as 2.5 cm) that are usually subpleural, peripheral, and basal in distribution. They can be subdivided into:
microcystic honeycombing
macrocystic honeycom...

Pulmonary fibrosis
Pulmonary fibrosis is the preferred general term for the permanent replacement of lung parenchyma by connective tissue and is typically associated with functional impairment. A variety of insults cause focal or diffuse lung injury (mechanical, infectious, inflammatory and iatrogenic). Lung repai...

Paracicatricial emphysema
Paracicatricial emphysema is a morphological sub type of pulmonary emphysema.
Pathology
In this form, emphysematous spaces are seen adjacent to areas of scarring with latter usually caused by silicosis, granulomatous infection, tuberculosis, pneumonia or pulmonary infarction.
Radiographic fe...

Carbon monoxide transfer coefficient
Carbon monoxide transfer coefficient (often abbreviated as KCO) is a parameter often performed as part of pulmonary function tests. It is also often written as DLCO/VA (diffusing capacity per liter of lung volume) and is an index of the efficiency of alveolar transfer of carbon monoxide.

Macklin effect
The Macklin effect refers to pneumomediastinum caused by alveolar rupture and pulmonary interstitial emphysema tracking to the mediastinum along the peribronchovascular interstitium. This is typically seen in blunt chest trauma or asthma.
Pathology
A sudden rise in intra-alveolar pressure can ...

Upper lobe bronchiectasis
Distribution of bronchiectasis can help in narrowing the differential diagnosis. Upper lobe bronchiectasis is typically seen in:
cystic fibrosis
tuberculosis
Rarely it may be seen with non-tuberculous mycobacterial infection (e.g. MAC infection 2). Traction bronchiectasis in the upper lobes c...
