On histopathological examination of these cases, all contained the fatty tissue, whereas interlobular
fibrosis was seen in 21 patients and pseudoangiomatous stromal hyperplasia was detected in 8 patients (11).
AQP-1 reacted strongly with the cells in the interlobular
vein of liver, and positive reactivity with the ductular structures was also observed (Fig.
According to the previous CT studies for ATL patients and HTLV-1 carriers (8, 15, 16), CT scans were assessed with regard to each of the following patterns: centrilobular opacities, nodule (not centrilobular, <3 cm in diameter), ground-glass attenuation, consolidation, bronchiectasis, thickening of bronchovascular bundles, bronchial wall thickening, interlobular
septal thickening, honeycombing, crazy-paving appearance, enlarged lymph nodes ([greater than or equal to]1 cm in diameter of the short axis, subclassified into mediastinal, hilar, supraclavicular, and axillary nodes), pleural effusion, pericardial effusion, and subcutaneous nodules.
Marked intra-alveolar and interlobular
edema of the pulmonary septa was observed in all cases.
Under the influence of estrogen, interlobular
connective tissue collects mucosal edema, which then leads to its swelling and hyalinization.
Doppler USG was measured with peak systolic velocity (PSV), end diastolic velocity (EDV), and acceleration time (AT) was measured with Doppler USG in Doppler angle 30[degrees]-60[degrees] in the right and left common renal and interlobular
arteries (Figure 1).
DAH is often characterized by pathy zones of consolidation that rapidly coalesced to form air-space consolidation of both lungs in the background of ground-glass opacity and interlobular
thickening which could be the early sign of pulmonary capillaritis of ATRA syndrome. As shown in this case, early recognition, instantaneous initiation of dexamethasone and daunorubicin, and adequate respiratory support if needed are the key of successful treatment and may help to improve its prognosis.
In multicentric Castleman disease these plasma cells are distributed along the "lymphatic route," such as the area around the bronchovascular bundle, vein, and interlobular
septum, whereas in LIP they are mainly distributed along alveolar septal walls.
In TTUS, the artifact generated from the thickened interlobular
septa at lung surface was considered as TTUS B-line.
Some lobules showed wide central caseification necrosis (Figure 2b) and some contained inflammatory cell infiltrations including neutrophil leukocytes and mononuclear cells extending from the center to the interlobular
areas (Figure 2a).
The bile duct hyperplasia and marked periductular/ interlobular
fibrosis was also evident (Fig.
Studies on CT findings of CMV infections have reported a combination of GGO, consolidation, nodules, poorly defined small centrilobular nodules, bronchial dilatation, and thickened interlobular
