Background: Chest high-resolution computed tomography [HRCT] is considered the "gold" standard for radiological diagnosis of interstitial lung disease [ILD]. However, it is not available in all health care facilities and its high cost is a limitation for its wide use. Ultrasound could provide a suitable alternative. Aim of the work: To detect the role of transthoracic lung ultrasonography [LUS] in diagnosis and assessment of ILD and to correlate it with HRCT as a gold-standard diagnostic modality. Methods: This included fifty patients who were admitted with clinical features suggestive of ILD. All were clinically evaluated [by full history and physical examination], submitted to pulmonary functions, arterial blood gases, lung ultrasound and HRCT. Results: The total sum of B-lines was 72.64 ± 39.45 and the total positive chest areas [> 3 B-lines] 6.47 ± 2.35. The most common ultrasound finding was thick pleural line. Finally, there was positive [proportional], moderate, significant correlation between Warrick's score [HRCT] and B-lines distance [LUS]. However, Warrick score correlated negatively with each of six-minute walk test, partial arterial oxygen tension and forced vital capacity. Conclusions: Lung ultrasound as a diagnostic modality for ILD reveled that, it is a useful tool, as there was good correlation between LUS and HRCT. LUS is cheap, accessible and radiation-free diagnostic tool. It could play a stand alone or a complementary role in the diagnosis and monitoring of ILD.

“…Sarac et al [15] reported a lower Warrick score, and their patients had mild to moderate disease. In Farag et al [16] revealed no association between B-lines scores and different grades of disease severity discovered by HRCT.…”

Background Transthoracic ultrasound (TUS) can potentially give important complementary information in particular conditions like bedside rapid diagnostic evaluation of dyspneic patients who commonly present to emergency (ER) units. Objective Assessing the significance and diagnostic utility of B-lines and pleural line abnormalities detected on TUS among patients presented to the ER unit for the assessment of dyspnea against high-resolution computed tomography findings. Patients and methods A prospective observational study including 240 consecutive patients was conducted. TUS was done for patients presenting to the ER for the assessment of dyspnea. B-lines and the pleural line were evaluated by a linear and convex transducers. Sonographic findings were reported against high-resolution computed tomography findings, which was considered the gold standard. Results Slightly rough, fringed, irregular, interrupted, wavy, coexistence of more than one abnormal type of pleural line were detected in 30.8%, 35.4%, 19.2%, 17.9%, and 30% of cases, respectively. Warrick score classified patients with interstitial lung disease to mild (44.6%), moderate (36.3%), and severe (19.2%). Diffusing capacity for carbon monoxide (DLCO% predicted) and total lung capacity (TLC% predicted) predicted showed negative correlation with Warrick score (r=−0.66, r=−0.48 respectively, P≤0.001 for both) and positive correlation with distance between B lines (r=0.31 and 0.30 respectively, P≤0.001 for both). Warrick score at a cutoff more than 7 showed 96.3% sensitivity and 64.3% specificity. Distance between B lines at cutoff more than 3 mm had 100% sensitivity and 40.4% specificity. Cutoff more than 3 for B lines number/scan showed 92.6% sensitivity and 31% specificity. Pleural thickness at cutoff more than 2 mm showed 100% sensitivity and 34% specificity. Abolished lung sliding showed 96.3% sensitivity and 50% specificity. Conclusion TUS is an important tool for the diagnosis and assessment of pulmonary disorders. B-lines number and distance, pleural line abnormalities, lung sliding, and pleural thickness added diagnostic value for the ER assessment of dyspneic patients.

Background Diffuse parenchymal lung diseases (DPLDs) constitute a heterogeneous group of lung diseases characterized by variable degrees of inflammation and fibrosis. In some DPLD, significant morbidity and unfavorable prognosis, comparable to those of neoplastic diseases, are seen. Efficient and safe methods for the diagnosis of DPLD are needed. Aim of the work To assess the characteristic features of DPLD in Fayoum Governorate based on clinical, radiological, and functional assessment. Patients and methods This study included 100 patients with undiagnosed DPLD who were selected from the Chest Department, Fayoum University Hospital, during the period from June 2015 to June 2016. All patients were subjected to written informed consent, full medical history, echocardiography, collagen profile, arterial blood gas analysis, spirometry, 6 min walk test, high-resolution computed tomography (HRCT) of the chest and lung biopsy when indicated. Results Out of the 100 patients included in the study, 72 (72%) were women, 28 (28%) were men, 15 (15%) were smokers, and 73 (73%) had a history of raising birds. The mean age was 45.4 years(range, 8–85 years). HRCT showed different patterns of parenchymal affection. Idiopathic interstitial pneumonia was the predominant diagnosis (51%), followed by DPLD of known cause (33%), then granulomatous DPLD (12%), and lastly other rare forms of DPLD (4%). Conclusion The historical ‘gold standard’ of histological DPLD diagnosis is replaced by a ‘dynamic integrated approach’ using multidisciplinary discussion. The optimal HRCT technique for the evaluation of DPLD is crucial. HRCT of the chest was the diagnostic tool in 75% of the study patients without the need for biopsy.
