Differential diagnosis of sarcoidosis
Tuberculosis is probably the most important differential diagnosis to sarcoidosis. It also typically affects the lungs and can have serious consequences if not diagnosed. Other possible alternative diagnoses include various cancers of the lymphatic system, such as Hodgkin’s disease or non-Hodgkin’s lymphomas. Furthermore, pathological accumulation of foreign particles can lead to similar symptoms. These include quartz dust, which can lead to so-called silicosis if inhaled over many years, for example during mining operations.
Summary
Sarcoidosis can be diagnosed by various methods. These include first of all the medical history, i.e. the doctor-patient consultation, and a physical examination to determine the exact symptoms. When the blood is examined, various parameters can provide information about the disease.
Probably the best known method of diagnosing sarcoidosis is an X-ray of the lungs. In addition, a bronchoscopy, i.e. a lung endoscopy, a pulmonary function test and a CT of the lungs can be helpful. To assess the involvement of organs other than the lung, an ECG, an MRI and a PET scan can be used.
