CTICasesAdenocarcinoma Masquerading as Chronic Infection
Imaging findings
Persistent focal consolidation and reticulation in a smoker with underlying emphysema and fibrosis, initially attributed to recurrent infection due to positive sputum cultures. Serial imaging showed gradual expansion/filling-in, eventually confirmed as adenocarcinoma.
Key takeaways
In patients with underlying fibrosis, assume that persistent, focal, or progressive consolidations are malignant until proven otherwise, despite positive infectious workups.
