An intracranial lesion is a caused by atherosclerosis, and affects the
neurovascular arteries that are in the brain. These arteries supply
blood with oxygen and other nutrients to the brain to make it function
properly. An intracranial lesion occurs when the inner walls of the
arteries thicken due to a buildup of cholesterol, fatty deposits,
calcium, and other elements. This material is known as plaque.
As plaque forms, the vessel narrows. When the vessel narrows (for
example, with physical effort or mental stress), blood flow through the
vessel is reduced so less oxygen and other nutrients reach the brain.
This reduced blood flow may cause mild to severe headaches or other
symptoms. Complete blockage (no blood flow) of a neurovascular artery
can result in a stroke.
Several factors increase the risk of getting atherosclerosis in the
neurovascular arteries. These factors include a history of smoking, high
cholesterol, diabetes, high blood pressure, being overweight, and a
family history of stroke or heart disease.
