CTICasesAngioinvasive Mucormycosis
Imaging findings
Stroke CT and brain MRI show bilateral embolic cerebral infarctions. Chest CT demonstrates abrupt cutoff of the left lower lobe pulmonary artery and vein, associated with a large hemorrhagic/necrotic pulmonary infarction (bird's nest sign).
Key takeaways
Mucormycosis is a highly aggressive, angioinvasive fungal infection in neutropenic patients. It invades both pulmonary arteries and veins, causing thrombosis, severe pulmonary infarction, and systemic embolization (e.g., to the brain).
