CTICasesAngioinvasive pulmonary mucormycosis (Rhizopus)
Imaging findings
CT scan of a patient with AML and profound neutropenia shows a large right lung mass with peripheral consolidation (halo and reverse halo signs) and lack of contrast enhancement due to extensive vascular invasion and pulmonary infarction.
Key takeaways
Pulmonary mucormycosis is a highly aggressive angioinvasive infection in neutropenic patients. The presence of reverse halo signs and unenhancing pulmonary infarction on contrast CT is strongly suggestive of angioinvasion.
