This finding can allow honeycombing to be distinguished from paraseptal emphysema in which subpleural cysts usually occur in a single layer. Honeycombing and traction bronchiectasis in UIP. The case on the left shows subpleural honeycomb cysts in several contiguous layers.

Emphysema 80 patients and paraseptal emphysema in 11 of 31 patients (35%). Honeyc ombing, which is one of the most common findings of usual interstitial pneumonia, was present in 24 of the 31 patients (77%). In 2005 Cottin et al (Cottin V, et al., 2005) conducted a retrospective study of

7 honeycombing, mixed microcystic and macrocystic honeycombing, and combined emphysema and honeycombing (Figure 1). UIP usually shows mixed microcystic and macrocystic honeycombing. This suggests that the disease results from repeated episodes of focal damage to the alveolar epithelium (10, 11). Microcystic honeycombing is found in early UIP, This finding can allow honeycombing to be distinguished from paraseptal emphysema in which subpleural cysts usually occur in a single layer. Honeycombing and traction bronchiectasis in UIP. The case on the left shows subpleural honeycomb cysts in several contiguous layers. As compared with honeycombing, which may present as multiple layers of cysts stacked upon one another, emphysema presents as a single layer of holes without stacking.7 Furthermore, emphysematous holes are typically not hexagonal; therefore, the shape of the cysts and their propensity to stack can help to distinguish one from the other.7 Paraseptal emphysema refers to a morphological subtype of pulmonary emphysema located adjacent to the pleura and septal lines with a peripheral distribution within the secondary pulmonary lobule. The affected lobules are almost always subpleural, and demonstrate small focal lucencies up to 10 mm in size.

They are considered to be a prestage of microcystic honeycombing. Honeycombing is classified into microcystic honeycombing, macrocystic honeycombing, mixed microcystic and macrocystic honeycombing, and combined emphysema and honeycombing (Figure 1). UIP usually shows mixed microcystic and macrocystic honeycombing.

Paraseptal emphysema is characterized by involvement of the distal part of the secondary lobule and is therefore most striking in a subpleural location (Figs. 6-23 to 6-25, 20-4 to 20-6, and 20-15 to 20-17). Areas of subpleural paraseptal emphysema often have visible walls, but these walls are very thin; they often correspond to interlobular septa.

Paraseptal emphysema can cause damage that over time leads to empty spaces in your lung tissue. If they get too big, you may be at risk for a collapsed lung. But that happens rarely. As compared with honeycombing, which may present as multiple layers of cysts stacked upon one another, emphysema presents as a single layer of holes without stacking.7 Furthermore, emphysematous holes are typically not hexagonal; therefore, the shape of the cysts and their propensity to stack can help to distinguish one from the other.7 Paraseptal emphysema typically affects adults between the ages of 18 and 30.

Idiopathic pulmonary fibrosis (IPF) and chronic obstructive pulmonary disease ( COPD) are two types of chronic lung disease. Find out the main differences 

There are cases that show paraseptal emphysema in the upper and middle lobes, although there is typical honeycomb lung in the lower lobes. In these cases, these different pathologic processes are often continuous with each other in the subpleural zone. Paraseptal emphysema is localized near fissures and pleura and is frequently associated with bullae formation (area of emphysema larger than 1 cm in diameter). Apical bullae may lead to spontaneous pneumothorax.

2016-02-25 · Brillet et al. identified three HRCT patterns in 61 patients with CPFE: i) progressive transition (38 %) with diffuse emphysema (centrilobular and/or bullous) and zone of transition between bullae and honeycombing, ii) paraseptal emphysema (21 %) with predominant subpleural bullae of enlarging size at the bases and iii) separate processes (23 %) with independent areas of fibrosis and emphysema.

Paraseptal emphysema is usually distinguishable from honeycombing because the cystic spaces occur in a single layer, whereas honeycomb cysts usually occur in multiple layers. Areas of paraseptal emphysema can also be larger (bullae) than typical honeycomb cysts. When a reticular pattern and honeycombing predominantly is localized in the inferior aspects definite UIP most probably is the cause .
