Objective The aim of this study was to determine the diagnostic value of lung ultrasound (US) in the detection of interstitial lung diseases (ILDs), and to assess the correlations of these features with diagnostic parameters of the disease. Background Chest US can be used as a complementary method for the diagnosis of ILDs especially in situations where chest computed tomography is not available, where bilateral B lines, thickened pleura, irregular pleura, and subpleural lesions are found. Patients and methods This study was carried out on 53 patients ranging in age from 47 to 60 years (21 men and 32 women) and 23 apparently healthy persons as a control group (12 men and 11 women). All cases were subjected to a full assessment of history, clinical examination, laboratory investigations, arterial blood gases, pulmonary function test, plain chest radiography, chest high-resolution computed tomography, and transthoracic US. Results Our results showed that there were bilateral B-lines in combination with a thickened, irregular pleura and subpleural lesions, which are strongly suggestive of the presence of ILD. There was a statistically significant correlation between B-lines distance in millimeter, pleural line thickness in millimeter, pleural line irregularity, and abolished lung sliding that found by chest US and severity grades of high-resolution computed tomography according to the findings of semiquantitative scoring findings in ILDs patient group. Conclusion Bilateral B-lines in combination with a thickened, irregular pleura and subpleural lesions are strongly suggestive of the presence of ILD. These lines are not found in controls.
