CTICasesNocardiosis
Imaging findings
CT scan of a heart transplant recipient demonstrates a well-circumscribed, homogeneous lung mass near an airway with minimal surrounding inflammatory change or mass effect. Biopsy confirmed a nocardial abscess (nocardioma).
Key takeaways
Nocardia infections in immunocompromised patients, such as transplant recipients, can present as single, clean-appearing, well-circumscribed masses (nocardiomas) that mimic post-transplant lymphoproliferative disorder (PTLD) or fungal infections like Cryptococcus.
