Ideally, screening for CAPA entails using a combination of computed tomography chest imaging and Aspergillus antigen tests on BAL and serum including GM ELISA or lateral-flow tests [28], or aspergillus PCR [29]. Whilst characteristic CT features of invasive aspergillosis such as nodules with halo sign were seen in 17.6% of severely ill COVID-19 patients, they were not confirmed to be IPA [30]. Given the lack of typical invasive aspergillosis features on CT in IAPA, the absence of classical findings such as cavitation should not be used to exclude CAPA; however, their presence can help support the diagnosis and reduce the burden of evidence placed on mycological investigations.
