Overview
In comparison with chest x-ray, HRCT is more specific and proved useful in the diagnosis of sarcoidosis and evaluation of complications, such as aspergilloma . Chest CT findings include parenchymal perilymphatic nodules.
CT
CT is useful in diagnosis of sarcoidosis[1]. A CT scoring system for sarcoidosis has been described and has been suggested to assess severity of disease.Typical HRCT findings that suggest sarcoidosis include parenchymal nodules and opacities that represent conglomerations of these nodules that have a perilymphatic distribution along the bronchovascular bundles as well as in subpleural locations[2][3][4]. Honeycombing in HRCT is associated with decreased DLcO and an increased A-a PO2 gradient[5][6]. .
