Imaging findings
Radiographs and CT showed extensive findings suggestive of lung parenchymal disease. Biopsies of the lingula revealed iron deposition in the lung parenchyma, leading to a diagnosis of siderosis.
Key takeaways
This case illustrates siderosis resulting from occupational exposure to nitric oxide and ferric chloride during engraving work. The patient's symptoms correlated with starting a new job. Inhaling nitrogen oxides can cause chemical burns to the lungs, and exposure to ferric chloride can lead to iron deposition. Clinical presentation may mimic other conditions like CHF, but does not respond to standard therapies.
