Letter to the Editor

Dear Editor-in-Chief,

We would like to thank Dr. Brinjikji and colleagues for their interest and comments on our recently published letter to the editor, “Developmental venous anomaly (DVA) depicted incidentally in fetal MRI and confirmed in post-natal MRI” [1]. In their observation, Brinjikji et al. defend that many DVA actually form in post-natal life and that DVAs are not necessarily congenital lesions.

This opinion is mainly based on a study by the same group where a significant positive association between age and DVA was found [2]. Although these results are indeed very intriguing, they also need to be interpreted with caution as the aforementioned study is not without limitations (including its retrospective nature, dependence on reporting, absence of information regarding the clinical indication of the exams except in case of tumor or epilepsy, significant differences regarding the number of patients included in each age group, absence of healthy control group, and image...
