Clinical Presentation: Two years after a clinical and bronchoscopicdiagnosis of
stage I sarcoidosis, the patient suffers fromexertional dyspnea and a dry cough.
Comment: Sarcoidosis is a systemic, diffuse granulomatosis ofunknown etiology.
The initial pulmonary lesion is amacrophage-lymphocyte alveolitis. Granulomas appear later
withinthe alveolar wall, along the bronchi, in the pleural space andinterlobular septa. There
are 5 radiological stages in sarcoidosis,relevant to the prognosis: stage 0 ñ normal chest
x-ray stage I -adenopathy without any radiological evidence of pulmonaryinvolvement
stage II - adenopathy associated with pulmonary signsstage III ñ pulmonary disease
without adenopathy stage IV - signsof pulmonary fibrosis
Description: The initial frontal chest X-ray shows bilateralsymmetrical hilar
adenopathy. CT images confirm the presence ofenlarged mediastinal and hilar lymph
nodes. The follow-up chestX-ray two years later shows a new bilateral
perihilarreticulonodular infiltrate and peripheral nodules in the mid-zones.The CT images
show persisting mediastinal and hilar lymph nodeswith subpleural nodules.
