Based on these non-specific CT findings there is a broad differential diagnosis and additional clinical information is mandatory for the interpretion of the HRCT. Since this patient is a smoker we first think RB-ILD. Honeycombing is a CT imaging descriptor referring to clustered cystic air spaces (between 3-10 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: The walls of the cysts are well-defined and often thick (1-3 mm) 4. 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 2015-09-28 · The centrilobular emphysema group exhibited a significantly higher extent of emphysema (P < 0.001) and a lower extent of interstitial lung disease (P < 0.002), reticular pattern not otherwise specified (P < 0.023), extent of ground glass opacity with traction bronchiectasis (P < 0.002), extent of honeycombing (P < 0.001) and coarseness of fibrosis (P < 0.001) than the paraseptal group. The centrilobular emphysema group exhibited a significantly higher extent of emphysema (P < 0.001) and a lower extent of interstitial lung disease (P < 0.002), reticular pattern not otherwise specified (P < 0.023), extent of ground glass opacity with traction bronchiectasis (P < 0.002), extent of honeycombing (P < 0.001) and coarseness of fibrosis (P < 0.001) than the paraseptal group. Paraseptal emphysema usually involves the distal part of the secondary lobule and is therefore most obvious in subpleural regions.

Paraseptal emphysema vs honeycombing

Ground-glass attenuation areas are also commonly present. 2 Sometimes, ground-glass attenuation is the sole abnormality suggesting interstitial lung disease and biopsy is required in this setting 10 to differentiate CPFE from other smoking-related … The centrilobular emphysema group exhibited a significantly higher extent of emphysema (P < 0.001) and a lower extent of interstitial lung disease (P < 0.002), reticular pattern not otherwise specified (P < 0.023), extent of ground glass opacity with traction bronchiectasis (P < 0.002), extent of honeycombing (P < 0.001) and coarseness of fibrosis (P < 0.001) than the paraseptal group. 2020-06-07 Areas of centrilobular or paraseptal emphysema that are superimposed on the ﬁne interstitial ﬁbrosis pattern can appear very similar to honeycombing (Fig. 2a). Obvious paraseptal emphysema in the upper lobes may indicate that the cystic appearances in the lower lobes are, in fact, likely to represent emphysema admixed with ﬁbrosis, which 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. Giant bullae occasionally cause severe compression of adjacent lung tissue.

2a).

Paraseptal Emphysema vs Honeycombing Paraseptal emphysema Honeycomb cysts occur in a single layer at the pleural surface may occur in several layers in the subpleural lung predominate in the upper lobes predominate at the lung bases unassociated with significant fibrosis Associated with other findings of fibrosis. Usual interstitial pneumonia pattern in two patients with idiopathic pulmonary fibrosis. a) At low magnification, subpleural/paraseptal scars obscuring the alveolar architecture alternate with normal lung (“patchy fibrosis”). At the top, two areas of honeycombing can be observed (haematoxylin and eosin stain, 20×). Additional findings in this patient are paraseptal emphysema in the upper lobes and some subtle septal thickening in the basal parts. Based on these non-specific CT findings there is a broad differential diagnosis and additional clinical information is mandatory for the interpretion of the HRCT.

Honeycombing has been reported in up to 40 % of NSIP . HC may be observed in approximately 10 % of patients with asbestosis (Fig.

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.

PSE occurs in a single layer, while honeycomb cysts are often in multiple layers. The walls of PSE are thinner than those of honeycombing, and the cystic spaces are usually larger. PSE is unassociated with signs of fibrosis such as traction bronchiectasis and irregular reticulation, which are typically seen with honeycombing. When a reticular pattern and honeycombing predominantly is localized in the inferior aspects definite UIP most probably is the cause . Other pathologies in the lung parenchyma as cystic lung diseases and emphysema, especially the paraseptal type may mimic honeycombing, and sometimes it is a challenge by CT to make a definitive diagnosis Paraseptal emphysema is usually distinguishable from honeycombing because the cystic spaces occur in a single layer, whereas honeycomb cysts usually occur in multiple layers.

On this page: 2015-01-01 · In the spared parenchyma emphysematous changes appeared, and changes mimicking honeycombing probably represent paraseptal emphysema. PSE is unassociated with signs of fibrosis such as traction bronchiectasis and irregular reticulation, which are typically seen with honeycombing. Honeycombing usually predominates at the lung bases, while PSE is most severe in the upper lobes. One caveat: both PSE and honeycombing may be seen in the same patient. Bullous Emphysema Honeycombing is a CT imaging descriptor referring to clustered cystic air spaces (between 3-10 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: The walls of the cysts are well-defined and often thick (1-3 mm) 4.

Subpleural honeycomb cysts typically occur in several contiguous layers. This finding can allow honeycombing to be distinguished from paraseptal emphysema de ("honeycombing"), samt förekomst av så kallade fibroblast foci dvs cellfattiga områden med en företrädesvis subpleural och paraseptal.
