The reversed halo sign extending the spectrum of atypical radiological manifestations in sarcoidosis
Mucormycosis, an invasive fungus with a variety of clinical presentation, is a devastating infection in immunocompromised host. Here an unusual case of pulmonary mucormycosis is introduced in an immunodeficient patient in which pneumothorax was followed by reversed halo sign (RHS). The clinicians, who visit immunocompromised persons with pneumothorax, should be considerate to take immediate ima...
In 23 leukemia patients with proven (n = 17) or possible (n = 6) pulmonary mucormycosis (PM), the presence of reversed halo sign on computed tomography was strongly associated with the positivity of quantitative polymerase chain reaction assays targeting Mucorales in the serum, confirming the value of these two tools for the diagnosis of PM in this setting.
The reversed halo sign (RHS) may sometimes be seen in patients with cryptogenic organizing pneumonia (COP), but is rarely associated with other diseases. Herein, we present a case of a 21-year-old woman with chronic eosinophilic pneumonia, with high resolution computed tomography (HRCT) finding of RHS. This is an unusual and rare presentation of chronic eosinophilic pneumonia.
