A case of a 62-year-old man with known longstanding pulmonary antracosilicosis, with associated hepatosplenic antracosilicosis, is presented. A CT scan of the upper abdomen revealed multiple calcifications within the spleen, and to a lesser degree within the subcapsular region of the liver, as well as "egg-shell" calcifications of abdominal lymph nodes, most noticeable at the splenic hilum. Although histopathologically not proven, the similar appearance of the calcified hepatosplenic nodules to the small round calcifications scattered throughout the lungs, as well as the typical "egg-shell" morphology of the calcified abdominal lymph nodes, should raise the suspicion of hepatosplenic antracosilicosis.
The authors revealed differences in pulmonary volumes, bronchial patency of bronchi at various levels, integral time of air transit in individuals having early anthracosilicosis and silicosis signs vs in healthy miners. During stage 1 of anthracosilicosis and silicosis respiratory function progressively deteriorates and demonstrates moderate disorders. When compared to anthracosilicosis ones, patients having polymetallic dust silicosis showed more significant decrease of the studied parameters.
