Dizziness and Abnormal CT Scan

Hello, I'm a 35 year old female.  I've been having dizziness on and off for about a month.  After a few doctors visits and false diagnoses (low blood pressure, bppv) I finally got a CT Scan with and without contrast.  The CT with contrast was normal, but the CT without contrast reads as follows:


The head CT shows no intracranial hemorrhage, extra-axial fluid collection or mass lesion. Mild bilateral deep white matter hypodensities are present, greater in the left parietal lobe suggesting chronic small vessel ischemic changes. A focus of acute
infarct is not completely excluded. The ventricles are normal in size and shape. The basal ganglia and posterior fossa appear unremarkable.
Mild vascular calcifications are present. The mastoid air cells and paranasal sinuses appear clear. No acute soft tissue or bony abnormality detected.

I'm over a week out from my follow up appointment to discuss this with my doctor.  Can someone please help me understand what this means?

That's what your doctor is for.  It doesn't sound like much is wrong, but trying to decipher these kinds of tests is very hard, and doctors often don't follow the radiologist report.  There are a lot of reasons people get dizzy.  Anxiety can cause it.  Inner ear problems can cause it.  Miniere's Disease can cause it.  Internal bleeding, such as from an ulcer, can cause it.  Too many things can cause it to know what's up.  Have patience, and let's hope your doc is a good one.
