CTICasesPulmonary Nocardiosis in a Heart Transplant Recipient
Imaging findings
CT chest in a heart transplant recipient shows multiple large, round, bilateral pulmonary nodules and masses, mimicking a fungal infection. Sputum cultures grew Nocardia species.
Key takeaways
Nocardiosis is an opportunistic bacterial infection that can mimic invasive fungal infections (like Aspergillus or Cryptococcus) on CT, presenting as multiple nodules or consolidation. It typically occurs in transplant recipients after prophylaxis (e.g. Bactrim) has been discontinued or reduced.
