Developmental Venous Anomaly: Benign or Not Benign - PMC
Developmental venous anomalies (DVAs), previously called venous angiomas, are the most frequently encountered cerebral vascular malformations. However, DVA is considered to be rather an extreme developmental anatomical variation of medullary veins than true malformation.
Developmental Venous Anomalies - Johns Hopkins Medicine
DVAs also may be called venous angiomas or benign variations in venous drainage. Some healthcare providers refer to them as caput medusae. This is a Latin term that means head of Medusa . These unusual vein formations can occur anywhere in the body. But they are found most often in the brain or spinal cord. What causes developmental venous ...

2023年3月30日 · SUMMARY: Developmental venous anomalies (DVAs) are the most common slow-flow venous malformation in the brain. Most DVAs are benign. Uncommonly, DVAs can become symptomatic, leading to a variety of different pathologies. DVAs can vary significantly in size, location, and angioarchitecture, and imaging evaluation of symptomatic developmental venous anomalies requires a systematic approach. In ...
