CTICasesInvasive lung adenocarcinoma mimicking chronic infection in HIV
Imaging findings
Chest CT shows a massive right upper lobe mass causing destruction of the adjacent second, third, and fourth ribs, in a patient with HIV/AIDS who had a history of Pneumocystis jirovecii pneumonia in the same lobe 4 years prior.
Key takeaways
In patients with HIV, lung cancer can occur at a younger age and behave more aggressively. Pre-existing scars from infections (such as PCP) can mask developing adenocarcinoma, leading to delayed diagnosis.
