Introduction.
Currently, about two hundred diseases with signs of
interstitial lung diseases have been identified, which is about 20% of all lung
diseases, with half of them being of unclear origin [1].
Objective
: to identify radiographic changes in non-specific interstitial
pneumonia.
Material and methods of the study
. A retrospective analysis of the case
histories of 200 patients with non-specific interstitial pneumonia (NIP) was
conducted. All patients underwent general clinical standards of research
according to ICD-10, in addition, all underwent high-resolution X-ray and
computed tomography images.
Results and discussion
. In 26 patients, X-ray examination revealed
increased lung roots on both sides, stringiness, and decreased local
transparency. In 30 patients, along with increased roots, decreased
transparency of both lungs was found, similar to bilateral pneumonia. In 27
patients, general X-ray signs characteristic of chronic obstructive bronchitis
were found. CT revealed typical signs of nonspecific interstitial pneumonia,
including decreased transparency of the lung tissue, such as "ground glass",
traction bronchiectasis and bronchioloectasis, thickening of the interlobular
septa, decreased volume of the lower lobes, and (often, but not always)
"honeycomb lung" [2].
Possible findings in patients with NIP include consolidation foci. This
symptom may reflect the simultaneous presence of organizing pneumonia, with
which NIP overlapped in 50% of patients in one study. The course of the
pathology may be accompanied by periods of increased clinical symptoms,
usually taken as an exacerbation of NIP. During this period, CT shows expanded
"ground glass" zones and new consolidation areas. The presence of symmetrical
thin subpleural stripes of preserved lung tissue (subpleural sparing) was noted,
followed by reticular and inflammatory changes.
Conclusions.
Radiological studies using HRCT technologies indicate that
patients with nonspecific interstitial pneumonia are characterized by the

predominance of "ground glass" and the absence of "honeycomb lung" in the
cellular subtype, and in the fibrous or mixed subtype, all four main radiological
syndromes are expressed to varying degrees simultaneously, as well as (often,
but not always) "honeycomb lung". Also characteristic is the presence of
symmetrical thin subpleural stripes of preserved lung tissue, followed by
reticular and inflammatory changes.
