A granuloma is a small area of chronic inflammation that can form after infection, irritation, or immune disease.
Granulomas themselves often cause no symptoms and may be found incidentally on a scan. When symptoms occur, they usually come from the underlying condition, such as cough, fever, weight loss, or pain.
Imaging helps show where granulomas are located, whether they look old and inactive or need closer attention, and whether there are other related findings in the lungs or other organs.
Imaging may detect granulomas in the lungs, liver, spleen, or elsewhere, often as small nodules or calcified spots.
Management depends on the cause and whether the finding is old and harmless or needs further evaluation.
This entry explains the finding. The next step is having a radiologist interpret your specific scan, not a general definition.
