FIGURE 1. Grayscale lung ultrasound examination (linear probe,
12 MHz, and the small parts preset) shows Septal Pattern of early CPE
(8) in a 14-year-old boy with acute heart failure caused by
non-diagnostic and untreated rheumatic carditis (A and B) and in a
5-year-old girl with systemic inflammatory disease in course of sepsis
in the absence of functional and / or organic alteration of the
myocardium (C, D and E).
Figures A and B show the SIS pattern of the posterior basal right and
left fields respectively; those C, D and E show that of the posterior
basal left and right fields (C and D) and lateral basal right (E)
respectively.
The pleural line is regular (arrowhead). There are no short vertical
artifacts and subpleural consolidations. B-lines or long vertical
artifacts (arrows) are multiple, and separated / non-confluent, laser
like artefacts, with gravitational course spreading from the pleural
line to the bottom of the screen and they show an internal sequence of
alternating horizontal bands. They are distributed homogeneously in the
explored fields ”without spared areas”.
CPE, cardiogenic pulmonary edema; SIS, sonographic interstitial
syndrome.
FIGURE 2. Grayscale lung ultrasound examination (linear probe,
12 MHz, and the small parts preset) in a child of 14 months with viral
lower respiratory tract infection caused by RSV and Bocavirus. The
figures above and below show the SIS pattern located on the upper and
lower fields respectively of the left posterior lung fields.
The pleural line is irregular. There are small subpleural consolidations
(hypoechoic areas, arrows) and below areas of white are evident
(arrowheads). B-lines or long vertical artifacts are multiple and
confluent; they do not have a gravitational trend and do not have a
laser arefacts-like appearance; they create areas of white lung
(arrowheads) and are unevenly distributed in the explored fields.
RSV, Respiratory Syncytial Virus; SIS, sonographic interstitial
syndrome.
FIGURE 3. Grayscale lung ultrasound examination (linear probe,
12 MHz, and the small parts preset) shows a SIS picture in a completely
healthy infant.
Figures A and B show the SIS pattern of the left anterior upper and
lower fields respectively; those C, D show that of the upper posterior
left and upper lateral left fields respectively.
The pleural line is regular (arrowheads) with no subpleural
consolidations. Figures B and D show short vertical artifacts (black
arrows). B-lines or long vertical artifacts (withe arrows) are single
and separated / non-confluent in figures A and B, while in figures C and
D they are multiple and tend to merge. They are distributed unevenly
”with spared areas” where a normal ultrasound pattern with A lines
(asteristisks) is clearly visible.
SIS, sonographic interstitial syndrome.
