Imaging findings
CT chest in a heart transplant recipient shows multiple, new, well-defined nodules in the middle and lower lobes, which developed rapidly. Biopsy and culture grew Nocardia nova.
Key takeaways
Nocardia is an opportunistic bacterial infection (Gram-positive branching rod) that classically occurs in immunocompromised hosts, such as transplant recipients. It typically presents as multiple well-defined nodules or masses that can cavitate, and must be differentiated from invasive fungal infections and PTLD.
