Abstract: Developmental venous anomalies (DVAs) are the most frequently encountered brain parenchymal vascular malformation. They are thought to arise during intrauterine development; however, the pathogenesis of these lesions remains unknown. A unique case documenting the postnatal evolution of a DVA in the left cerebellum of a young child is presented and the current literature on the pathogenesis and imaging characteristics of these anomalies is reviewed. Our case strongly suggests that the processes contributing to DVA maturation can extend into the postnatal period.
