Algorithm to assess uveitis in patients with suspected sarcoidosis (From Sève et al., Sem Resp Crit Care Med, 2020). Abbreviations and notes: ACE: angiotensin converting enzyme; BAL: bronchoalveolar lavage; EBUS: endoscopic ultrasound-guided fine-needle aspiration of intrathoracic nodes; MSGB: minor salivary-gland biopsy; 18F-FDG PET: 18-fluorodeoxyglucose positron-emission tomography. * if old age at uveitis presentation, presence of synechia and an elevated ACE; ** If EBUS not previously performed. The yield of diagnoses from a bronchoalveolar lavage and a trans-bronchoscopic biopsy in patients with an abnormal PET and normal chest CT is unknown. Negative mediastinal lymph-node biopsies from patients with mediastinal lymphadenopathy are, in our experience, exceptional.
