Silicosis is a common occupational disease. We present a 64-year-old male patient suffering from symptomatic silicosis due to compression of the pulmonary arteries by enlarged hilar lymph nodes. Clinical symptoms and diagnostic imaging modalities are described, with emphasis on cross-sectional imaging. MR angiography and perfusion MRI of the lung in silicosis are described, and their diagnostic value in pneumoconiosis is discussed.
