Abstract
- We analysed post enhanced chest CT scans of 5 pathologically proved sarcoidosis patients attempting to differentiate sarcoidosis from other diseases showing multiple lymph node enlargements. The distribution of intrathoracic lymphadenopathy was diffuse and bilateral in all cases. However the largest nodes were located atsubcarinal, hilar and right paratracheal group (2R, 4R, 10R). Hilar node involvements were typically bilateral and symmetric, Anterior mediastinal and subcarinal regions, which were previously belived in unusual location, showed enlarged nodes in all cases. The appearances of the nodes were well-defined, homogenous soft tissue mass and thenodes did not show matted appearance. The pulmonary infiltration was bilateral and diffuse reticulonodular pattern. Our observations suggest that in cases of homogenous, discrete lymph node enlargements, particularly when subcarinal, bilateral hilar and right paratracheal node groups are involved, sarcoidosis should be included i the differential diagnosis.
