Imaging findings
A chest radiograph revealed a faintly visible, fairly round lesion in the left lower lobe. A subsequent CT scan confirmed a well-defined nodule in the lung base. The lesion appeared smooth and round.
Key takeaways
In solid organ transplant patients presenting with lung nodules, a broad differential includes opportunistic infections such as Nocardia, Aspergillus, PTLD, and Cryptococcus. Cryptococcus gattii is known to affect pets and marine mammals, with potential exposure through animal droppings. The treatment typically involves a long course of antibiotics, such as voriconazole, for six months to a year.
