There are low density lesions seen throughout the renal parenchyma. Some of theses appear to represent cysts. There s a low density lesion in the right lower pole of the kidney which measures approximately 8 mm that does not appear to represent a simple cyst. There is a 3.5 cm right adrenal mass, which demonstrates heterogeneous echotexture. The overall Hounsfield units are suggestive of an adenoma; however, the standard deviation and heterogeneity of the mass does raise some concern for a possible superimposed neoplasm. This is on a CT report of the abdomen. Can you shed some light on what this means?
