What is a hypo dense lesion in the kidney mean?

A hypodense lesion in the kidney refers to an area that appears darker than the surrounding tissue on imaging studies, such as a CT scan. This typically indicates that the lesion has a lower density, which may suggest fluid-filled structures like cysts or potential pathological changes such as tumors or abscesses. Further evaluation, including follow-up imaging or biopsy, may be necessary to determine the exact nature of the lesion.
