Focus on Sarcoidosis
The utility of endobronchial ultrasound-transbronchial needle aspiration in patients with suspected extra-pulmonary sarcoidosis without thoracic lymphadenopathy
Diagnosis of extra-pulmonary sarcoidosis can be difficult, and a biopsy is usually required. We evaluated the utility of endobronchial ultrasound-transbronchial needle aspiration (EBUS-TBNA) in patients with suspected extra-pulmonary sarcoidosis with thoracic lymph nodes ≤10 mm on chest computed tomography (CT) and no or minimal pulmonary infiltrates.Cardiac sarcoidosis: Diagnosis confirmation by bronchoalveolar lavage and lung biopsy
The diagnosis of cardiac sarcoidosis (CS) is difficult to ascertain due to the insensitivity of endomyocardial biopsy. Current diagnostic criteria require a positive endomyocardial biopsy or extra-cardiac biopsy with clinical features suggestive of CS. Common tests for diagnosis of pulmonary sarcoidosis include bronchoalveolar lavage (BAL), lung and mediastinal lymph node (MLN) biopsies. Our objective was to determine the diagnostic utility of these tests in patients with suspected CS and without prior history of pulmonary involvement.
