Pulmonary complications were suspected in all patients and chest CT scans were taken within a month of death. We examined the association between autopsy and CT findings in 48 patients who were diagnosed as IPA (<jats:italic>n<\/jats:italic>\u2003=\u200317), candidosis (<jats:italic>n<\/jats:italic>\u2003=\u20034), zygomycosis (<jats:italic>n<\/jats:italic>\u2003=\u20032), infiltration of hematological malignancy (<jats:italic>n<\/jats:italic>\u2003=\u200312), bacterial pneumonia (<jats:italic>n<\/jats:italic>\u2003=\u20036), cytomegalovirus pneumonia (<jats:italic>n<\/jats:italic>\u2003=\u20032), pulmonary hemorrhage (<jats:italic>n<\/jats:italic>\u2003=\u20032), or pulmonary congestion (<jats:italic>n<\/jats:italic>\u2003=\u20031). Patients with IPA showed a variety of CT findings, including halo (<jats:italic>n<\/jats:italic>\u2003=\u200313), nodules (<jats:italic>n<\/jats:italic>\u2003=\u200314), granular shadows (<jats:italic>n<\/jats:italic>\u2003=\u20033), masses (<jats:italic>n<\/jats:italic>\u2003=\u20036), consolidations (<jats:italic>n<\/jats:italic>\u2003=\u20039), wedge\u2010shaped consolidations (<jats:italic>n<\/jats:italic>\u2003=\u20031), and cavitation (<jats:italic>n<\/jats:italic>\u2003=\u20032). In contrast, 0, 11 and two of the 31 patients without IPA showed halo, nodules and masses, respectively. These signs were more frequently observed in IPA patients than in non\u2010IPA patients. The CT halo, especially, seemed to be specific for IPA in hospitalized neutropenic patients with hematological malignancies who developed antibiotic\u2010resistant fever. For CT findings other than these three signs, there were no significant differences between IPA\u2010 and non\u2010IPA patients.<\/jats:p>","DOI":"10.1046\/j.1439-0507.2002.00770.x","type":"journal-article","created":{"date-parts":[[2003,3,12]],"date-time":"2003-03-12T14:49:31Z","timestamp":1047480571000},"page":"287-294","source":"Crossref","is-referenced-by-count":38,"title":["The value of the chest computed tomography halo sign in the diagnosis of invasive pulmonary aspergillosis.
