Imaging findings
The patient had a 40-year history as a metal machinist with exposure to tungsten and cobalt. Radiographs and thin-section CT scans showed bilateral reticulation with conspicuous subpleural cystic changes in the peripheral portion of the upper lobes, along with traction bronchiectasis and bronchiolectasis in the lower zones.
Key takeaways
Hard metal interstitial lung disease should be suspected in machinists presenting with interstitial lung disease and distinctive upper-lobe predominant cystic changes. Clinical history of exposure is essential for diagnosis as the radiographic findings are consistent with this specific pneumoconiosis.
