Hard metal interstitial lung disease (HM-ILD) is a rare form of interstitial lung disease caused by aerosolized particulates containing cobalt inhaled during the manufacture or grinding of hard metal. The high-resolution computed tomography (HRCT) appearance of HM-ILD includes reticulation, traction bronchiectasis, and large peripheral cystic spaces in a mid and upper lung distribution. This appearance, along with a consistent occupational exposure, should specifically suggest the diagnosis of HM-ILD.
