What is a hyperdense lesion?

A hyperdense lesion is an area on imaging studies, such as CT scans, that appears denser than the surrounding tissues, indicating increased radiopacity. This can be due to various factors, including the presence of calcifications, hemorrhage, or certain types of tumors. The hyperdensity often suggests that the lesion may contain a higher concentration of minerals or proteins. Understanding the characteristics of a hyperdense lesion is crucial for diagnosing underlying conditions.
