A minor reaction was localized in the interlobular
Ground-glass attenuation (n=10, 36%) was the most frequent finding in lung parenchyma, which was followed by bronchial wall thickening (n=9, 32%), centrilobular opacities (n=8, 29%), lung nodules (n=8, 29%), and interlobular
septal thickening (n=7, 25%) (Figs.
Pleura and interlobular
septa are thickened by neutrophils, fibrin and edema.
The fibrosis is mainly seen beneath the pleura and along the interlobular
septum (Figure 2, A).
The differential diagnosis of US B-lines includes cardiac manifestions caused by the thickening of the interlobular
septa, such as in pulmonary edema.
Tuberculin skin test was 5 mm; computed tomography (CT) of the thorax revealed interlobular
septal thickening, bilateral hilar and mediastinal lymphadenopathy, and mosaic attenuation of the lungs.
The B lines in this case occur when ultrasound waves meet thickened, edematous interlobular
The presence of interstitial edema causes smooth thickening of the interlobular
septa and thickening of the bronchovascular bundles.
Kono et al., "Scavenger cells with Gram-positive bacterial lipoteichoic acid infiltrate around the damaged interlobular
bile ducts of primary biliary cirrhosis," Journal of Hepatology, vol.
The similar results regarding perilobular and interlobular
inflammation and bile-duct proliferation significantly are showed in group III compared with the others (P < 0.05).
ducts can be hypoplastic due to subnormal bile flow.
The sampled portal tracts showed the appropriate constellation of artery, vein, and interlobular
bile duct without evidence of ductopenia.
