We appreciate the interest and comments by Drs. Mamourian and Wallace regarding our article on developmental venous anomaly (DVA) presenting atypical findings on susceptibility-weighted imaging (SWI).¹ Our experience with DVA with relatively higher flow on SWI is limited; however, we agree that prudent evaluation should be applied for interpretation of DVA on SWI because the clinical course of such vascular malformations might show intracranial hemorrhages and epilepsy.² Additional studies are also needed regarding the SWI appearance of DVAs, including large ones, as in our letter.
