Hi!
Why you've been examined with ct scan? Did you experience some symptoms?
This bright spots can be tumor, but also there are some non-tumor masses and lesions that can mimic tumors.
I'll suggest you to ask your doctor about MRI because is
the most sensitive non-invasive way of imaging the brain and can create better picture of lesions than CT.
There are also spots found in healthy individuals, which are not related to any ongoing disease process. These are often called unidentified bright objects.
