A case of venous congestion associated with developmental venous anomaly (DVA) in a 5-year-old girl who presented with acute deterioration of consciousness is reported. Susceptibility-weighted imaging revealed abnormal structures connected to the central collector of a DVA, which were not shown on other sequences. These structures were considered to be presumably thrombosed medullary veins.
