Figure 2. a–c.

(Case 1) Pulmonary mucormycosis manifesting as masses with the “reversed-halo” sign in a 47-year-old male patient with myelodysplastic syndrome. Chest CT taken at admission (a) shows masses with the “reversed-halo” sign in both lower lobes. Internal cavitary changes are evident within the masses. Two days later, a CT image taken during percutaneous needle biopsy (b) shows masses with thick walled cavitations surrounded by growing ground-glass opacities. Although the patient was put on antifungal agents, these masses grew and showed more extensive cavitary changes with air-fluid level on the follow-up CT taken 19 days later (c). He underwent right lower lobectomy for further treatment; however, the patient died.
