Diagnosis | Criteria |
Proven | Histopathological or cytopathological examination of lung tissue showing hyphae from needle aspiration or biopsy specimen with evidence of associated tissue damage OR positive culture result for Aspergillus from a sample obtained by sterile procedure from the lung AND clinically or radiologically abnormal site consistent with infection |
Probable | Host factor (table 1) AND mycological evidence (positive Aspergillus microscopy or culture from the sputum or BAL or positive antigen assay#) AND clinical criteria consistent with infection¶ |
Possible | Host factor (table 1) AND clinical criteria consistent with the infection¶ |
BAL: bronchoalveolarlavage. #: Positive antigen assay: galactomannan antigen detected in plasma, serum, BAL fluid or cerebrospinal fluid, or β-d-glucan detected in serum. ¶: Clinical criteria: new characteristic infiltrates on computed tomography imaging (dense, well-circumscribed lesion(s) with or without a halo sign, air-crescent sign, or cavity), tracheobronchitis seen by bronchoscopy, or noncharacteristic new infiltrates with a specific pulmonary symptom or sign (such as pleural rub, pleural pain, haemoptysis).
