The aim of the study was: 1/ to evaluate the usefulness of HRCT-score as a guide method in selection of the most reliable lung region for VATS biopsy in DPLD, 2/ to examine the correlation between HRCT-score and semi-quantitative histopathological results in idiopathic interstitial pneumonias (IIPs) based on HP-score, 3/ to evaluate the homogeneity of fibrosis by estimation of cytological and immunological results of TGF-ß1, MMP-9, PGE2 and PGD2 in double BAL from two different lung segments: with the most and with the least extensive involvement estimated by HRCT-score. Examined group consisted of 31 patients in whom diagnosis of DPLD was not established by clinical, radiological, physiological and non-invasive methods. The two different lung segments were indicated by HRCT-score for BAL and VATS biopsy. Regarding as histopathological results there were 17 IIPs and 14 granulomatous diseases (GDs). Twenty eight of patients showed nonhomogenous distribution of HRCT changes, with a predominance of linear opacities in IIPs in lower lobes (p = 0,05279) and higher HRCT-score in IIPs in lower lobes (p < 0,01). In IIPs the odds ratio for obtaining better histopathological result was 12,5-times higher depending on higher activity in HRCT-score, also confirmed by logit model (p = 0,0609). In GDs the histopathological result was obtained in 84,62%, independently of HRCT-score and with no ; predilection for any lobe. A semi-quantitative histopathological result in IIPs is correlated only with few parameters of HRCT; a fibrosis-score with linear opacities (χ2 p = 0,042) and a cellularity-score with intensity of changes (χ2 p = 0,0192) and ground-glass opacities (χ2 p = 0,026). There was not found any correlation between total HRCT-score and HP-score. A higher amount of neutrophils and eosinophils and a higher concentration of TGF-ß1, MMP-9 and PGD2 in BAL may occur good markers of fibrosis in IIPs, but only the higher concentration of TGF-ß1 (p = 0,018) and the higher amount of eosinophils (p = 0,016, ANOVA) are significantly correlated with HRCT-score.
