HIGH-RESOLUTION CT CHEST FINDINGS IN RARE OCCUPATIONAL LUNG DISEASES – AN OVERVIEW

Abstract

CT has an increasing role in the radiologic evaluation of occupational/ environmental
lung disease. The high-resolution CT (HRCT) findings of siderosis, talcosis, berylliosis,
calcicosis and hypersensitivity pneumonitis are described. The purpose of this article is
to describe the high-resolution CT (HRCT) features of rare occupational lung diseases.
The HRCT chest was done from June 2012 to June 2013 in 50 patients with
occupational history related to the following diseases with a minimum of 5 years of
occupational exposure with symptoms of cough with/ without sputum. No standardized
quantification scheme is available for occupational lung diseases using CT.
