pulmonary ossification in a case of usual interstitial pneumonia. Chest CT image shows bilateral subpleural reticulation and honeycombing, both more evident than the more cranial sections, suggesting apico-basal gradient. Bronchiectasis are also present (arrows).

Clinical and
radiological features of lung disorders related to connective-tissue diseases: a pictorial essay. Axial (A, C), coronal (B) and sagittal (D) HRCT images demonstrate—in an RA patient—the presence of a florid honeycombing, involving more than 50% of the lung. This finding is typically due to macrocystic spaces (white arrows) and has been defined as “exuberant honeycombing sign”

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) . They represent an irreversible finding commonly seen in diffuse pulmonary fibrosis (usual interstitial pneumonia UIP).

Pathology

Honeycombing consists of enlarged air spaces with thick fibrotic walls lined by bronchiolar epithelium and often filled with mucin and inflammatory cells .

History and etymology

The term “honeycomb lung” is thought to have originated in the 19century in Germany and is thought to have first appeared in 1949 in a study by N Oswald and T Parkinson .
