A40 year old man, a non-smoker, was referred to us on account of chest radiograph abnormalities that had been discovered during thepreoperative evaluation before an Achilles tendon repair. He had no respiratory complaints or significant past medical history. He had been working as a silver polisher for the last 20 years.
His routine blood investigations were normal. The chest radiograph (fig 1) and the high resolution computed tomography (HRCT) lung scan (fig 2) are shown. Spirometry and arterial blood gases were normal.
What do the chest radiograph and the HRCT of the lung show?
What is the differential diagnosis of the HRCT scan appearance and the likely diagnosis in this case?
