honeycombing histopathologically. 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.

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. Honeycombing has been reported in up to 40 % of NSIP .

Paraseptal emphysema vs honeycombing

In 2005 Cottin et al (Cottin V, et al., 2005) conducted a retrospective study of 2017-02-16 2016-09-13 Before a lung biopsy was performed, the alternative diagnosis may have been combined pulmonary fibrosis and emphysema (CPFE) because of the paraseptal emphysema and pulmonary fibrosis. CPFE and RBILD were both closely associated with smoking, but CPFE generally presents with severe dyspnoea, has a poor prognosis, frequently complicated by PH, preserved FEV 1.0, and severely … The CT imaging shows moderate centrilobular emphysema as well as mild paraseptal emphysema. Furthermore, there are basilar predominant subpleural cysts and reticular markings representing fibrosis and honeycombing. Given the constellation of these findings, a diagnosis of combined pulmonary fibrosis and emphysema is made. 3.

As such, because several conditions may display a HRCT pattern similar to UIP, radiologists should always indicate their level of diagnostic confidence and use all available tools (e.g. multiplanar reconstruction and comparison with previous examinations, if available) in order to discriminate between honeycombing, traction bronchiectasis or bronchiolectasis, and subpleural paraseptal emphysema.

Recent findings: CPFE is a recently identified syndrome in smokers or ex-smokers characterized by dyspnea often severe, preserved lung volumes, severely impaired gas exchanges, and an increased risk of pulmonary hypertension associated with a dismal prognosis There is an association between emphysema and osteoporosis.

Giant bullae occasionally cause severe compression of adjacent lung tissue. Honeycombing has been reported in up to 40 % of NSIP . HC may be observed in approximately 10 % of patients with asbestosis (Fig. 17.4 ) along with findings of irregular interlobular septal thickening, intralobular interstitial thickening, subpleural dot-like or branching opacity, and ground-glass opacity (GGO), not to mention of pleural plaques [ 6 ].

A: paraseptal emphysema in the upper lung zones, distant to fibrosis (“isolated” emphysema); A′: honeycombing in the lower zones in the same patient. In the present case, apparent paraseptal emphysema both in upper and lower lobe was found, that differs from previous studies. Before a lung biopsy was performed, the alternative diagnosis may have been combined pulmonary fibrosis and emphysema (CPFE) because of the paraseptal emphysema and pulmonary fibrosis. 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%).

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. Areas of paraseptal emphysema can also be larger (bullae) than typical honeycomb cysts.

Distal Acinar Emphysema. See paraseptal emphysema. Dynamic Expiratory HRCT. HRCT scans performed during expiration to diagnose air trapping or airway collapse (15,16,20,44). Emphysema. Permanent, abnormal enlargement of airspaces distal to the terminal bronchiole, accompanied by the destruction of their walls .

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.

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.

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 … 2015-09-28 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 2015-04-07 Pathologically, paraseptal emphysema is often accompanied by fibrosis in its walls . There are cases that show paraseptal emphysema in the upper and middle lobes, although there is typical honeycomb lung in the lower lobes.

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.

7 Furthermore, emphysematous holes are typically not 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. Distinguishing between honeycombing and paraseptal emphysema may be difficult, especially when coexisting on a single scan.
