Typically, LG patients with lung involvement can present with pulmonary infiltration and may later develop a reversed halo sign, a focal round area of ground-glass attenuation and surrounding airspace consolidation of crescent shape....
This is the first reported case of a patient who developed fungal pneumonia caused by Cunninghamella bertholletiae (= C. elegans) following cord blood transplantation and who showed a reversed halo sign on a chest computed tomography scan (CT). In addition, the pathological findings related to the reversed halo sign are described in detail for the first time. The patient died due to respiratory...
Computed tomography scans of documented pulmonary mold infections were reviewed for the presence of the reversed halo sign, a focus of ground-glass attenuation surrounded by a solid ring. The reversed halo sign was an early sign, seen in approximately 4% of patients with pulmonary mold infections, usually with zygomycosis.
