Abstract

The pulmonary manifestation of sarcoidosis has a great variability and is notorious for mimicking many other interstitial lung diseases. Knowledge of pulmonary manifestations is important in diagnosing saroidosis because thoracic involvement is present in over 90 % of patients. In this chapter, classical findings on chest X-ray and HRCT are described as well as multiple uncommon findings in radiology. The most common findings are bilateral hilar lymphadenopathy, reticulonodular pattern, perilymphatic distribution of nodules, and predominant upper- and middle lobe parenchymal abnormalities. Uncommon findings are unilateral lymphadenopathy, reticular pattern, excessive ground glass opacities, pleural disease, solitary mass, and predominant lower lobe parenchymal abnormalities. Furthermore, the appearance of pulmonary hypertension and necrotizing sarcoid granulomatosis will be described. Finally, imaging of pulmonary sarcoidosis with positron emission tomography with 18F-Fluordeoxyglucose (18F-FDG PET) will be discussed.
