When we read chest CT reports, we are often bothered by a small nodular shadow in the lung. Further reading reveals that radiologists often interpret this small nodule as a possible large inflammatory granuloma. What is inflammatory granuloma? First of all, when you come across such a report, congratulations are in order. By “inflammatory granuloma possible”, radiologists mean that the nodule is not a malignant tumor, but a benign lesion. Since there are so many tumors with benign lesions, it is written as “inflammatory granuloma possible”. Secondly, the radiologist saw a shadow, and his report of “inflammatory granuloma possible” is only a pathological speculation. Pathologically, “inflammatory granuloma” refers to a cell mass formed by fibroblasts together with inflammatory cells. The cause is infection by various microorganisms, autoimmune abnormalities, and physical and chemical damage. The outcome depends on the causative factors and usually dissipates completely, with some scarring. Now, do you understand? If you see inflammatory granulomatous lesions in the future, don’t bother anymore.
