Step4 (H/D): 38 cases were diagnosed with high or definite confidence in TBLC-MDD.step1P: consensus pathological diagnosis without clinical and radiological information. step1R: consensus radiological diagnosis without clinical and pathological information. Step1C: Consensus clinical diagnosis without radiological diagnosis and pathological information Step2: Consensus clinical diagnosis with radiological diagnosis and without pathological information Step3: Consensus clinical diagnosis with radiological diagnosis and bronchoalveolar lavage analysis without pathological information Step4: MDD diagnosis with full information, including pathological diagnosis
