Imaging findings
Imaging in an immunosuppressed patient (due to chemotherapy for astrocytoma) reveals multiple large pulmonary masses of varying sizes, some of which are cavitary. These masses developed while on chemotherapy and responded well to antibiotics.
Key takeaways
Nocardia is a bacterium that frequently mimics fungal infections, presenting as large nodules, masses, and cavitary lesions in the lungs of immunocompromised patients. It's an important opportunistic infection to consider in this population. The characteristic imaging features can be effectively treated with appropriate antibiotics, leading to resolution.
