With increasing use of high field scanners and high resolution imaging protocols such as susceptibility-weighted imaging that can be used to visualize fine venous structures, understanding of the structure of fine venous anatomy has become important. Deep medullary veins drain into subependymal veins with four convergence zones and show parallel distribution patterns adjacent to the body or inferior horn and a radial pattern in the frontal horn or trigon of the lateral ventricle. Some disorders are related to deep medullary veins.
