CTICasesPulmonary Cryptococcosis
Imaging findings
Chest radiograph and CT show a solitary lung nodule in the left upper lobe near the hilum. The patient is a heart transplant recipient, and cryptococcal serology was positive.
Key takeaways
Cryptococcus is a common opportunistic fungal pathogen in solid organ transplant recipients. It typically presents as a solitary nodule or consolidation, which can mimic malignancy or other infections. Serologic testing is highly specific and sensitive, but biopsy is often performed to exclude other processes.
