The so-called transcerebral veins: appearance in three different cases
Summary
Dilated transcerebral veins, detected on CT/MRI, indicate elevated cerebral venous pressure. This finding may signal underlying dural vascular pathologies like fistulas or malformations.
Area of Science:
- Neurology
- Radiology
- Vascular Medicine
Background:
- Dilated transcerebral veins are not commonly recognized radiologic findings.
- Dural vascular pathologies can lead to increased cerebral venous pressure.
Purpose of the Study:
- To investigate the significance of dilated transcerebral veins observed on routine imaging.
- To correlate this finding with specific dural vascular pathologies.
Main Methods:
- Retrospective review of radiologic findings in three patients.
- Analysis of computed tomography (CT) and magnetic resonance imaging (MRI) scans.
- Correlation of imaging findings with diagnosed vascular pathologies.
Main Results:
- All three patients exhibited dilated transcerebral veins and dilated superior ophthalmic veins.
- Primary pathologies identified included vein of Galen aneurysmal malformation, dural sinus fistula with varix, and dural arteriovenous fistula.
- All patients presented with both arteriovenous fistula and sinovenous occlusion.
Conclusions:
- Dilated transcerebral veins may serve as a useful radiologic indicator of elevated cerebral venous pressure.
- This finding can suggest the presence of certain dural vascular pathologies on sectional imaging.
