Angiographic and computed tomographic correlation in cerebral venous angiomas

|September 1, 1980
Summary
Venous angioma, a rare brain vascular anomaly, is best diagnosed by understanding its venous phase appearance on imaging. Correlating computed tomography (CT) and angiographic findings aids accurate diagnosis.
Area of Science:
- Neurology
- Radiology
- Vascular Medicine
Background:
- Venous angioma is a rare congenital vascular malformation of the brain.
- Limited information exists on computed tomography (CT) findings for venous angiomas.
Observation:
- Angiography shows normal arterial and possible capillary phases.
- The key finding is the venous phase, revealing dilated medullary veins converging into a large drainage vein.
Findings:
- This study correlates angiographic and CT findings in two venous angioma cases.
- CT findings are consistent with the characteristic venous phase abnormalities seen on angiography.
Implications:
- Accurate diagnosis of brain venous angiomas can be achieved with knowledge of these imaging findings.
- Improved understanding of CT and angiographic appearances aids in diagnosing this rare vascular anomaly.
