Mayo Clinic doctors trained in brain and nervous system conditions (neurology), brain imaging (neuroradiology), and other areas diagnose your condition.
Your doctor may diagnose intracranial venous malformations during testing for other neurological conditions. You often don't experience symptoms.
Your doctor may order imaging tests to diagnose intracranial venous malformations or other neurological conditions.
- Computerized tomography (CT) scan. A CT scan creates a series of X-rays to create detailed, cross-sectional images of your blood vessels and your brain. Sometimes a doctor may inject a dye into a vein to view the blood vessels in greater detail (CT angiogram or CT venogram).
- Magnetic resonance imaging (MRI). In this test, magnetic and radio waves create detailed 3-D images of your blood vessels and your brain. Sometimes a doctor may inject a contrast dye into your blood vessels to make your blood vessels visible on the images (magnetic resonance angiography or magnetic resonance venography).
