Hypodensity in the Parietal Lobe



I recently had a CT-Scan with the results stating that I have a "non aggressive hypodensity deep in the white matter of the parietal lobe, likely a prominent perivascular space". I have tried to get the definition explained in layman`s terms, but have been unsuccessful in finding someone able to interpret the results. Could you please elaborate/explain what this means? I was medivac`d from Iraq (I am active duty army) before being able to consult with the radiologist to explain it to me. Thanks so much!


Thank you for visiting NetWellness.  I'm not sure what is meant by non-aggressive; however, a perivascular space is just space around a blood vessel and is typically normal.
