Introduction: Pulmunary baritosis is secondary to 
inhalation of barium dust with extremely dense, discrete 
opacities on the chest radiograph. Baritosis has been 
classified as a benign pneumoconiosis. We present an 
unusual case of pulmonary baritosis secondary to exposure 
to electrostatic paints. 
Case presentation: A 42 years old man was referred to the 
occupational medicine clinic with the respiratory 
symptoms of intermittent cough and exertional 
breathlessness. He had been spraying electrostatic and 
powder paint for 3 years. History and radiological features 
were consistent with the diagnosis of a pulmonary 
baritosis. 
Conclusion: It is necessary to take a detailed occupational 
history in individuals with respiratory symptoms. Medical 
surveillance should be performed at regular intervals to 
determine the adverse effect of barium sulfate.
