CTICasesLipoid Pneumonia
Imaging findings
A speculated mass-like lesion in the right middle lobe, which may mimic lung cancer but demonstrates characteristic fatty attenuation on soft tissue windows.
Key takeaways
Lipoid pneumonia can mimic malignancy (speculated appearance) but often reveals its identity through low, fat-equivalent attenuation values on CT. It may be asymptomatic or related to chronic aspiration.
