Aspergillus lateral-flow device; PM: post mortem; AML: acute myeloid leukaemia; RT: radiotherapy; NSCLC: nonsmall-cell lung cancer; NR: not recorded; V: voriconazole; I: isavuconazole; L-AmB: liposomal amphotericin B; C: caspofungin; A: anidulafungin; ND: no data; (+): positive result; (-): negative result. #: without histological evidence of “proven” IPA a patient host factor (e.g. recent neutropenia, haematological malignancy) is required to meet the probable/possible definition, corticosteroids must be given at ≥0.3 mg·kg−1 for ≥3 weeks to classify as a host factor result.Invasive aspergillosis is difficult to diagnose in critically unwell patients without traditional host factors because radiological changes are usually nonspecific (e.g. infiltrates, consolidation or nodules), with features such as halo sign, air-crescent sign or cavitation being rare [24].
