What is pseudo nodule?

A pseudo nodule refers to a lesion or mass that resembles a nodule but is not a true nodule in terms of its structure or nature. These can occur in various medical contexts, such as in imaging studies or pathological examinations, where they may appear similar to actual nodules but are often caused by factors like inflammation, artifacts, or other benign conditions. Pseudo nodules can lead to misinterpretation in diagnoses, so further evaluation is often necessary to determine their true nature.
