“…The relatively lower incidence of PMF calcifications in our patients might have been due to the shorter interval of symptom presentation. Marchiori et al reported a mean interval of 27.5 years for conglomerated mass development due to sandblasting, while in our study both exposure duration and latency period were very short [19]. In our study, a statistically significant correlation was determined between the exposure duration and CT grade and PMF presence.…”

The purpose of this study was to describe the findings of CT performed on denim sandblasters with silicosis. Fifty consecutive male patients with silicosis were evaluated. Their clinical data and pulmonary function tests (PFT) were obtained. The CT findings were recorded and the correlations between CT nodular profusion score and the other parameters were assessed. The diagnoses of the patients were classified as accelerated silicosis (n = 43) and acute silicosis (n = 7). The most common CT finding was centrilobular nodules. Twenty-three patients had complicated silicosis based on pleural involvement and presence of progressive massive fibrosis (PMF). Lymphadenopathy (LAP) was positive in 50% of the patients, with calcification in 24%. The CT grade was highly correlated with the clinical data such as exposure duration and PFT. Our findings suggest that the clinical manifestation of silicosis in denim sandblasters is severe. Although the duration of exposure is shorter the rate of complicated silicosis patients with pleural involvement was unexpectedly higher in the cases. Because the most common radiological appearance was nodules and the CT grading of the nodules was highly correlated with the clinical data, nodule grading may be used in the management of such cases.

“…Although chest X-ray is widely used to diagnosis and follow up the disease, there are several reports of CT detection of chronic silicosis [15,17-19]. Denim sandblasting is a novel cause of silicosis that has recently been reported in Turkey; thus, there are few reports in the literature on CT detection of accelerated [4] and acute silicosis [10,14] caused by denim sandblasting.…”

BackgroundDenim sandblasting is as a novel cause of silicosis in Turkey, with reports of a recent increase in cases and fatal outcomes. We aimed to describe the radiological features of patients exposed to silica during denim sandblasting and define factors related to the development of silicosis.MethodsSixty consecutive men with a history of exposure to silica during denim sandblasting were recruited. All CT examinations were performed using a 64-row multi-detector CT (MDCT). The nodules were qualitatively and semi-quantitatively analyzed by grading nodular profusion (NP) on CT images.ResultsSilicosis was diagnosed radiologically in 73.3% of patients (44 of 60). The latency period (the time between initial exposure and radiological imaging) and duration of silica exposure was longer in patients diagnosed with silicosis than in those without silicosis (p < 0.05). Nodules were present in all cases with centrilobular type as the commonest (63.6%). All cases of silicosis were clinically classified as accelerated and 11.4% had progressive massive fibrosis (PMF). Mild NP lesions were the most prevalent in all six zones of the lung. The NP score was significantly correlated with the duration of silica exposure, the latency period, presence of PMF, and pleural thickening. Enlarged lymphadenopathy was present in 45.5% of patients.ConclusionsThe duration of exposure and the latency period are important for development of silicosis in denim sandblasters. MDCT is a useful tool in detecting findings of silicosis in workers who has silica exposure.

“…The initial radiological manifestations consist of diffuse small nodules [6,42]. With progressive disease, conglomerations of nodules occur and result in large opacities known as conglomerated masses or progressive massive fibrosis [21]. The time of evolution and the occasional bilateral occurrence are useful in the differential diagnosis with tumors or tuberculosis [1,45].…”
