12] The probable cause for the decrease in PFT is the accumulation in peribronchial
lymphoid and connective tissues along with varying degrees of wall thickening and remodeling in terminal and respiratory bronchioles arising from each pathway.
A chest radiograph revealed moderate bilateral peribronchial
thickening with increased interstitial markings.
2] inhalation caused inflammatory cell infiltration in the peribronchial
and perivascular areas (H&E staining) and peribronchial
collagen deposition (MT staining) in PND1 and seven mice, although no obvious mucous cell metaplasia (AB-PAS staining) was observed at any time point (data not shown).
It is a consequence of fluid leakage into the interlobular and peribronchial
cell counts were performed according to Duan et al.
thickening and mucus plugging were also found [Figure 5].
Computed tomography scan demonstrates patchy airspace consolidation in a peribronchial
, lower lobe-predominant distribution.

The reticular pattern observed radiographically is often misinterpreted as diffuse fibrosis, peribronchial
fibrosis, honeycombing, suspected bronchiectasis, pleural-pulmonary scarring, or diffuse cystic lung disease.
Histologically, Langerhans cells typically proliferate in a peribronchial
fashion forming nodules mostly ranging from 1 to 5 mm in diameter, but some may be as large as 1.
Chest radiographs reveal transient perihilar or peribronchial
interstitial infiltrates in most children who are examined.
Chest X-ray and computed tomography (CT) showed calcified hilar lymph nodes on the left and peribronchial
nodular lesions of soft tissue density in the anterior and posterior segments of the right upper lobe.
