Here we report a case of putative invasive aspergillosis in a patient with COVID-19 associated ARDS, with growth of Aspergillus fumigatus and a positive Aspergillus-Ag test in endotracheal aspirate. The patient presented in this report had a two-week history of symptoms before he was admitted to the ICU. On ICU admission, a CT scan revealed a reversed halo sign that is usually suspicious for the presence of mucormycosis [7] but may also be found in other mold infections, particularly IPA [8]. Chest CT scans are a valuable tool for COVID-19 diagnosis and management. Ground-glass opacities with or without consolidations are observed in the majority of COVID-19 cases [9,10] but a reversed halo may be observed in some patients [9]. Similar to patients with severe influenza a halo or reversed halo sign may be indicative for presence of a pulmonary mold infection [11] and should therefore trigger further diagnostic steps to confirm or rule out IPA.
