Introduction: Sarcoidosis is a chronic i-nflammatory pulmonary disease with unknown etiology and variable clinical manifestations including, epithelial cell granulomas and alteration in tissue and organ functions. Materials & Methods: In this cross-sec-tional study, high-resolution computed tomography (HRCT) documents of pati-ents with proven sarcoidosis were re-evaluated. The results were analyzed using the software SPSS-11 and freq-uencies of the disease were reported as percentages and diagrams. Findings: Many typical and atypical manifestations of sarcoidosis such as bronchiectasis, lymphadenopathy, lym-ph node calcification and etc, were obs-erved at HRCT . Discussion & Conclusion: HRC may pr-ovide more advantages to identify and distinguish sarcoidosis from other mim-icking diseases. However, further inves-tigations are needed to scrutinize the matter.
