CTICasesInvasive Pulmonary Mucormycosis
Imaging findings
CT in a neutropenic stem cell transplant patient shows multiple rapidly growing nodules with a dense outer rim of consolidation and a ground-glass center (reversed halo/bird's nest sign). Biopsy of the lesions confirmed invasive Mucor infection.
Key takeaways
The reversed halo sign (or bird's nest sign) in a neutropenic patient is highly suggestive of angioinvasive fungal infection, particularly mucormycosis. Early recognition is vital because Mucor requires prompt surgical debridement and specific anti-fungal therapy.
