“…This takes into account not only the existence of nodular profusion (ICOERD), but also its spatial distribution in the cranio-caudal and anteroposterior axes (dorsal portion of the upper zones), as well as the size, shape and situation of the nodules in relation to the secondary pulmonary lobule: solid and well-defined, centrilobular and/or subpleural. Because volume-based CT with post-processing techniques (MPR and MIP) is an effective method for visualising the lung parenchyma, the classical findings of silicosis are more easily visualised by the method, even among individuals with low profusion of diminutive nodules 13 31 32…”

ObjectiveTo evaluate silicosis diagnosed through CT, with integration of clinical-occupational data, in silica-exposed workers presenting chest X-rays within International Labor Organization (ILO) category 0.MethodsCross-sectional study with 339 former gold miners, with comparable exposures and X-rays classified as ILO subcategory 0/0 (n=285) and 0/1 (n=54) were submitted to volume-based CT. The findings were classified according to the International Classification of HRCT CT for Occupational and Environmental Respiratory Diseases.ResultsA profusion degree of round opacities (RO)>1 was found in 22.4% (76/339) of the CT exams. After integrating the CT findings with clinical and occupational data, silicosis was diagnosed as follows: 43/285 (15.1%) and 14/54 (25.9%) in workers whose X-rays had been classified as 0/0 and 0/1, respectively. There was an upward trend towards longer exposures, reaching 38.9% when working more than 10 years underground and classified as 0/1 (p=0019). Those with presence of RO whose final diagnosis was not silicosis were mainly cases of tuberculosis or ‘indeterminate nodules’. Emphysema was found in 65/339 (19.1%), only 5 being detected in the X-ray.ConclusionVolume-based CT proved to be useful in the investigation of silicosis among individuals with a relevant exposure to silica, capturing diagnoses that had not been identified on X-rays. A response gradient of silicosis was showed by CT even in this population with ILO category 0 radiographs. It can be indicated based on quantitative and/or qualitative criteria of occupational exposure, especially considering the possibilities of low CT dosage.

“…The imaging approach with chest radiography can reveal small irregular opacities with a fine reticular pattern and may be associated with pleural thickening or plaques, however there are no known pathognomonic findings of asbestosis in this exam. The detection of parietal pleural thickening in the CT scan along with lung fibrosis is highly suggestive of asbestosinduced pulmonary fibrosis and can be very useful in differentiating it from idiopathic pulmonary fibrosis 13,14 .…”

“…The detection of parietal pleural thickening in the CT scan along with lung fibrosis is highly suggestive of asbestos-induced pulmonary fibrosis and can be very useful in differentiating it from idiopathic pulmonary fibrosis. 13,14 All forms of asbestos can cause asbestosis, a chronic and irreversible pneumoconiosis. Furthermore, they have been shown to be carcinogenic to humans.…”

Only six countries have banned the industrial use of asbestos in Latin America and the Caribbean. In fact, the industrial use of asbestos appears to be growing in this region. Asbestos is one of the most dangerous natural substances in the world, it is contained in several types of rocks (such as serpentinites, mafic and ultramafic rocks) but fibers can be released to the atmosphere both by natural and antropogenic sources. Six countries have banned the industrial use of asbestos in this region, we expected that laws established before 2007 would be less adherent to the 2007 WHO/ILO recommendations. In contrast, the Chilean law of 2001 is one of those that most adheres to international recommendations along with the Colombian law of 2021. Which means that the newest laws are not necessarily the strongest. This article aims to draw a regional overview of the laws against asbestos production in Latin America and the Caribbean, highlighting the strengths and weaknesses of each national policy. We recommend that countries that have already banned asbestos consider updating and strengthening their existing laws and develop clinical guidelines for the management, monitoring, and rehabilitation of asbestos-related diseases. The challenge of asbestos goes far beyond a prohibition law.

“…Chest radiography is often normal in early-stage disease but disease progression depicts small nodules and reticulation, typically with predominant distribution in the middle and upper lung (early) [ 115 ]. Reticulation, architectural distortion, honeycombing, and mass-like lesions are observed because of the coalescence of small nodules and lymphadenopathy [ 115 116 ].…”

Non-infectious granulomatous lung disease represents a diverse group of disorders characterized by pulmonary opacities associated with granulomatous inflammation, a relatively nonspecific finding commonly encountered by pathologists. Some lesions may present a diagnostic challenge because of nonspecific imaging features; however, recognition of the various imaging manifestations of these disorders in conjunction with patients' clinical history, such as age, symptom onset and duration, immune status, and presence of asthma or cutaneous lesions, is imperative for narrowing the differential diagnosis and determining appropriate management of this rare group of disorders. In this pictorial review, we describe the pathologic findings of various non-infectious granulomatous lung diseases as well as the radiologic features and high-resolution computed tomography imaging features.
