CTICasesCryptococcal Endobronchial Mass with Post-Obstructive Pneumonia
Imaging findings
Chest radiograph showed right-sided volume loss, suggesting right lower lobe collapse, and a spine sign on lateral view. CT revealed an endobronchial lesion in the bronchus intermedius, alongside a large, necrotic-appearing right lower lobe, representing post-obstructive pneumonia and/or atelectasis. Tree-in-bud nodules were seen in the right middle lobe.
Key takeaways
Infectious processes, particularly cryptococcosis, can present as mass-like endobronchial lesions mimicking tumors, causing post-obstructive pneumonia and atelectasis. Biopsy is essential for definitive diagnosis, as imaging features can be highly misleading.
