The
halo sign is a special computed tomography (CT) finding consisting of a macronodule surrounded by a perimeter of ground-glass opacity [35,36].
High-resolution CT visualization of the halo sign-indicative of a hemorrhagic pulmonary nodule-is an early sign of IPA with high sensitivity and specificity (6); however, differential diagnosis of the
halo sign is quite complex, as it may be observed as a result of infection with other microorganisms [(Candida spp., mucormycosis, cryptococcosis, cytomegalovirus (CMV), herpes simplex virus (HSV)] and other diseases, including Wegener granulomatosis, pulmonary metastases of hypervascular tumors, and Kaposi's sarcoma (7), (8).
Historically, the fat
halo sign has been associated with patients suffering from chronic inflammatory bowel disease.
(3) This appearance has also been dubbed the "reversed
halo sign" (Figures 1 through 4).

A computed tomography (CT) scan of the chest revealed a 3 cm x 3 cm, well-defined and round mass surrounded by a halo of ground-glass attenuation, namely the
halo sign, in the posterior basal segment of the right inferior lobe (Fig.
