INTRODUCTION: The aim of this paper was to evaluate the angioarchitectural factors that can induce concurrent cavernous malformation (CM) in the territory of developmental venous anomaly (DVA). METHODS: From January 2006 to December 2007, 21 patients with 23 CMs in the territory of DVA were retrospectively analyzed (M; F = 12; 9, mean age = 53.3). Gadovist®-enhanced three-dimensional spoiled gradient-echo images on a 3 T magnetic resonance (MR) scanner were used. We investigated the presence of angioarchitectural factors: factor 1, the angulated course of curved medullary or draining vein in the distal portion of CM; factor 2, narrowing of distal draining vein; factor 3, severe medullary venous tortuosity. These were also analyzed for control group of 23 subjects (M; F = 11; 12, mean age = 46). RESULTS: Factor 1 was demonstrated in 22 cases (97%) and the CM occurred in a position of 90° or less of an abrupt angulated medullary or draining vein in 15 cases (65%) of the study group. Factor 2 was found in 13 cases (57%) with the diameter reduction of 50% or more in five cases. The mean ratio of diameter reduction was 0.53. Factor 3 was found in 17 cases (74%). Analyzing the independent factors, the p values for factors 1 and 3 were <.05, i.e., statistically significant. If combination of more than two factors was present, the p values for all the combinations were <0.05, i.e., statistically significant. CONCLUSION: Anatomical angioarchitectural factors might be the key factors in causing concurrent sporadic CM within the territory of DVA by causing disturbance of blood flow
