Sarcoidosis is a multisystemic disease, which can involve any organ in the body. Similar to presenting signs and symptoms, imaging findings of sarcoidosis are diverse. Conventional radiography is useful in initial evaluation of pulmonary and musculoskeletal sarcoidosis.
Manifesting symptoms are organ dependent, but the most common ones include fatigue, arthralgias, diffuse pain syndromes, cough, dyspnea, wheezing, chest discomfort, rash, photophobia, scleritis, decreased visual acuity, weight loss, and fever.
Up to 2005 a total of 3152 had been included in the register; the most frequently reported diagnoses were Sarcoidosis (1063 patients). 80% of asymptomatic cases with occasional diagnosis were represented by pulmonary sarcoidosis; first symptoms at presentation of sarcoidosis were represented by dyspnea in 29.5%, cough in 18.6%, fever in 4.2%, others in 35.5%. Other interstitial lung diseases were COP (5,4%) and extrinsic allergic alveolitis (2,9%).
