Halo sign : chest
Dr Sajoscha Sorrentino and Dr Frank Gaillard et al.
The halo sign in chest imaging is a feature seen on lung window settings (typically HRCT) surrounding a pulmonary nodule or mass and represents haemorrhage. It is typically seen in angioinvasive aspergillosis.
Other entities that may give a halo sign include
