The CT halo sign in invasive aspergillosis
KEY CLINICAL MESSAGE In immunocompromised patients, the pulmonary computed tomography halo sign is highly suggestive of angioinvasive aspergillosis. Early recognition may be life-saving.
متن کاملAngioinvasive pulmonary aspergillosis after allogeneic bone marrow transplantation: clinical and high-resolution computed tomography findings in 12 cases.
The aim of this study was to present the clinical and high-resolution CT scan findings of angioinvasive pulmonary aspergillosis (APA) in 12 patients who underwent allogeneic bone marrow transplantation (BMT). The CT scans were reviewed by three chest radiologists who assessed the pattern and distribution of findings by consent. There were 7 (58%) female and 5 (42%) male patients, with aging bet...
متن کاملThe diagnostic value of halo and reversed halo signs for invasive mold infections in compromised hosts.
The halo sign is a CT finding of ground-glass opacity surrounding a pulmonary nodule or mass. The reversed halo sign is a focal rounded area of ground-glass opacity surrounded by a crescent or complete ring of consolidation. In severely immunocompromised patients, these signs are highly suggestive of early infection by an angioinvasive fungus. The halo sign and reversed halo sign are most commo...
متن کاملEarlier diagnosis of angioinvasive pulmonary mold disease: is computed tomography pulmonary angiography a new step?
Molds are a frequent causeofmorbidity and mortality in allogeneic hematopoietic stem cell transplant recipients and in patients with hematologicalmalignancies. Themost frequent molds involved in this setting are Aspergillus spp. and Zygomycetes [1]. Aspergillus and Zygomycetes infect the lower or upper respiratory tract after inhalation of spores. When host defenses are failing, the spores germ...
متن کامل[The halo sign in computed tomography images: differential diagnosis and correlation with pathology findings].
The halo sign is a circular area of ground-glass attenuation that is seen around pulmonary nodules at computed tomography (CT). Although the sign is most often an indication of pulmonary hemorrhage, it may also accompany other lesions associated with different disease processes. Examples are hemorrhagic nodules of infectious origin (mucormycosis, candidiasis, tuberculosis, viral pneumonia, and ...
