what is splenic hypodensity? what is meant by hypodense lesions?

Question

Tiny hepatic and splenic hypodensities

Answer 1

hepatic refers to liver, splenic refers to spleen
Hypo refers to "less than normal"
density refers to the normal mass of specific tissue.

so, your lesions are areas where the tissue of the organ has become less dense, more "friable", or weaker than the rest of the tissue.

Answer 2

A hypodensity on a CT (I am presuming that your question originates from a CT scan result) image means some portion of anatomy appears less dense than the surrounding tissue. The hypodensity may or may not be anything to worry about and can often be caused by a cyst. More than one would indicate different causes. It would be beneficial to have knowledge of the reason for the scan. By this I mean that trauma can cause symptoms which demand a scan, For example a possible hepatic laceration or a splenic injury. There are also certain physical symptoms for which a scan is required. Hypodensities in the spleen may be indicative of obstruction of the splenic veins. Hypodensities in the hepatic region normally require further examinations and / or tests to determine their cause.

Answer 3

Basically it is a Radiologist term to describe small areas in your spleen that appear to be less dense than what is normally expected. I imagine you had an imaging study(CT abdomen?) and you read the Radiologist's report.
