The spectrum of pulmonary sarcoidosis: variations of high-resolution CT findings and clues for specific diagnosis

Eur J Radiol. 2010 Jan;73(1):66-73. doi: 10.1016/j.ejrad.2008.09.038. Epub 2009 Feb 5.


Sarcoidosis is a systemic disease of unknown cause, characterized by widespread non-caseating granulomas. There is a wide spectrum of radiologic manifestations in pulmonary sarcoidosis, providing challenges to radiologists. However, recognition of the key features of sarcoidosis with knowledge of its pathologic background can often allow for specific diagnosis. In this review, we describe the variety of high-resolution CT findings in pulmonary sarcoidosis along with its pathologic features as the basis for radiographic manifestations, and discuss the key features on high-resolution CT for the specific diagnosis of pulmonary sarcoidosis.
