Lung ultrasoundClinical experience and scientific articles have shown that patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can be paucisymptomatic or asymptomatic at the time of diagnosis. In this paper, we will discuss two paucisymptomatic patients with blood tests suggestive for SARS-CoV-2 infection but with repeated negative nasopharyngeal swabs and without typical features of COVID-19 pneumonia on chest high-resolution computed tomography. In these cases, lung ultrasound helped to raise clinical suspicion of COVID-19 pneumonia and facilitate diagnosis.

Background:Dermatomyositis is a multi organ autoimmune disease wich is commonly complicated with interstitial lung disease. Chest high-resolution computed tomography (HRCT) is still considered the diagnostic gold standard for interstitial lung disease and is quantification, however he increasing use of lung ultrasound may play an important role in the future.Objectives:The aim of our study was to determine the diagnostic value of lung ultrasound in the detection and progression of interstitial pulmonary disease in patients with dermatomyositis.Methods:Twenty two subjects with dermatomyositis diagnosed according to the American College of Rheumatology criteria were enrolled (6 males, 16 females; mean age: 15,8 ± 8.8 years; range: 6 to 29 years). All subjects underwent high resolution computed tomography followed by transthoracic ultrasound for comet tail sign detection and pleural irregularity in order to predict the degree of interstitial lung disease. The modified transthoracic ultrasound assessment was performed at 06 thoracic regions each side. The Warrick score was calculated according standard high-resolution chest computed tomography images that were evaluated independently from each other by two thoracics radiologists.Results:A significantly positive correlation between transthoracic ultrasound and the severity of pulmonary involvement, as seen by the number of B lines (Spearman ‘s correlation coefficient = 0.80, p < 0.001), and the number of positive areas (regions wih more than 3 B lines) (Spearman ‘s correlation coefficient = 0.75, p < 0.001) were found. When compared with high-resolution chest computed tomography as the gold standard method, the sensitivity, specificity, of transthoracic ultrasound was 96.4%, 83,3% respectively. Addicionally the number of B lines (sum of 35 or more B lines) and a number of B lines positive areas (7 or more regions with at least 3 B lines) cut of allowed to discriminate the inflamatory pattern (ground glass) to those with structural pattern (honeycomb and pulmonary cysts).Conclusion:Our study showed that transthoracic ultrasound comet tails scoring system could be useful in the assessment of the pulmonary involvement in patients with dermatomyositis, and should be considered as a primary screening exam to exclude lung involvement, rather than routine chest CT scans in assimptomatic patients.Disclosure of Interests:None declared

Background: Interstitial lung disease (ILD) are group of pulmonary disorders characterized by inflammation and fibrosis of gas exchanging portion of the lung and diffuse abnormalities on lung radiograph. Conventional computerized tomography plays a limited role in evaluation of interstitial lung disease due to its inability to demonstrate fine parenchymal details. High Resolution Computed Tomography (HRCT) is currently the most accurate non invasive modality for evaluating lung- parenchyma. So, the purpose of the study was to assess high resolution computed tomography in the diagnosis of interstitial lung disease.Methods: 50 patients with clinical suspicion of interstitial lung disease who were referred to Department of Radio-Diagnosis and Imaging for diagnosis and evaluation were subjected to both conventional radiography and HRCT.Results: Majority of the cases i.e. 9 (18%) had honeycombing, 8 (16%) cases had crazy paving pattern and mosaic attenuation, 7 (14%) cases had miliary mottling, 6 (12%) cases had normal, 5 (10%) cases had fibrosis and ground glass haze, 2 (4%) cases had ground glass haze with Intralobular reticular opacities and 2 (4%), subpleural nodular opacities and 2 (4%) cases had B/lHilar lymphadenopathy.Conclusions: Ultimately all patients with clinical suspicion of ILDs should benefit from an HRCT scan of the thorax. High resolution computed tomography (HRCT) chest scans are essential to the diagnostic work-up since each ILD form is characterized by a specific pattern of abnormalities and a confident diagnosis can often be arrived at by HRCT alone or in correlation with the clinical symptoms. When HRCT findings are characteristic in appropriate clinical settings, HRCT may even obviate the need for a lung biopsy.

High Resolution Computed Tomography

Imaging plays a pivotal role in systemic sclerosis for both diagnosis management of pulmonary complications, and high-resolution computed tomography (HRCT) is the most sensitive technique for the evaluation of systemic sclerosis-associated interstitial lung disease (SSc-ILD). Indeed, several studies have demonstrated that HRCT helps radiologists and clinicians to make a correct diagnosis on the basis of recognised typical patterns for SSc-ILD. Most SSc patients affected by ILD have a non-specific interstitial pneumonia pattern (NISP) on HRCT scan, whilst a minority of cases fulfil the criteria for usual interstitial pneumonia (UIP). Moreover, several recent studies have demonstrated that lung ultrasound (LUS) is an emergent tool in SSc diagnosis and follow-up, although its role is still to be confirmed. Therefore, this article aims at evaluating the role of LUS in SSc screening, aimed at limiting the use of CT to selected cases.
