Test Results
Results and Interpretations
| Finding / Observation | Description (Example) | General Interpretation / Significance (Example) |
|---|---|---|
| Normal | Patent veins, clear brain tissue | No clots or lesions |
| Hypointense filling defect | Sinus blocked by clot | Possible CVST |
| Hyperintense lesion | Bright spot on scan | Tumor or hemorrhage—further tests advised |
| Vascular Malformation | A cluster of small medullary veins converging into a central vein, often forming a “caput medusae” pattern on post-contrast MRI sequences. | A common and typically benign congenital variant. DVAs are usually asymptomatic and require no treatment, but may coexist with cavernous malformations in rare cases. |
| Stenosis / Narrowing | The sigmoid sinus (or another major venous sinus) appears constricted or narrowed in diameter on MRI/MRV imaging. | May suggest intracranial venous hypertension, especially in patients with pseudotumor cerebri (IIH). Clinical correlation with symptoms and pressure measurements is needed. |
| Incidental Finding | A small, rounded, fluid-filled cyst in the region of the pineal gland, typically less than 10 mm in diameter. | A benign and common incidental finding. Rarely causes symptoms unless very large or compressing adjacent structures. Usually requires no follow-up or simple monitoring. |
