These cases all showed a small amount of pulmonary edema on the CXR, as evidenced by an enlarged hilar shadow or small patchy shadows (Figure 7).
(a) CXR before treatment: enlarged hilar shadows can be observed; (a1) corresponding CXR after treatment: the image returned to normal; (a2) corresponding LUS before treatment: the images were normal, and no B-lines were detected; (b) CXR before treatment: densified hilar shadows and small patch shadows can be observed in the upper left lung (white arrow); (b1) corresponding CXR after treatment: the image returned to normal; (b2) corresponding LUS before treatment: only a few B-lines (B-line score = 2) were detected.
Chest x-ray may show an absent hilar shadow, a shrunken affected lung, and a shift of the mediastinal structures to the affected side (2, 3).
Chest x-rays revealed absent hilar shadow and a shift of the mediastinal structures to the affected side (Fig.
Chest radiograph (Figure 1) showed hyperlucent right lung with decreased vascular markings and a small hilar shadow. CT (Figure 2) showed a hypoplastic pulmonary artery, bronchiectasis, hyperlucency on the right side and no pulmonary embolism.
Chest radiograph classically shows hyperlucency of the affected lung, decrease in vascular markings and small hilar shadow. Expiratory radiographs may reveal air trapping in the affected lung and contralateral mediastinal shift.
59 patients underwent chest X-ray examination, who were manifested often with increased and disorderly lung markings, atelectasis, patchy shadows, bronchitis, emphysema, luminal stenosis, and enlarged hilar shadows
(see Table 2 for details).
(9) However, with disease progression, (4) pleuroparenchymal thickening, with the thickness ranging from 4 to 15 mm, can be seen, and this is associated with subjacent fibrosis and elevated hilar shadows
. In advanced stage, fibrotic opacities with traction bronchiectasis extending to adjacent lobes with multiple bullae and large cysts in the upper fields can be identified.
A chest radiograph showed bilateral hilar shadows
Chest X-Rays revealed pulmonary vascular markings with blurring of the perivascular outlines, loss of hilar shadows
and sporadic patchy increases in parenchymal density.
Chest radiography of the patient showed minimal hilar shadows
with no other lung changes, but the heart shadow was increased and pericarditis was suspected.
The normal hilar shadows
should show individual vessels representing the pulmonary arteries and major veins, and very little else.
