Content provided by Healthwise
Results
Cranial ultrasound uses reflected sound waves to produce pictures of the brain and the inner fluid chambers (ventricles) through which cerebrospinal fluid (CSF) flows.
| Normal: | The size and shape of the brain appear normal. |
|---|---|
| The size of the brain's inner fluid chambers (ventricles) is normal. | |
| Brain tissue appears normal. No bleeding, suspicious areas (lesions), abnormal growths, or evidence of infection are present. | |
| Abnormal: | Bleeding in the brain may be present, which may indicate intraventricular hemorrhage (IVH). Repeated tests are often done to check the bleeding. |
| Suspicious areas or lesions around the brain's ventricles may be present. This may indicate periventricular leukomalacia (PVL), a condition in which the brain tissue around the ventricles is damaged. | |
| The brain and ventricles may be enlarged from the buildup of excessive amounts of cerebrospinal fluid (CSF). This may indicate hydrocephalus. | |
| Abnormal growths may be present, which may indicate a tumor or cyst. | |
| Suspicious findings may be present, which may indicate encephalitis or meningitis. |
