Figure 1. a–g.

Seven cases with a hyperdense paraspinal vein sign on computed tomography myelogram (CTM). Panels (a–g) show a single representative axial CTM image from each case (cases A–G). A contrast opacified hyperdense spinal/paraspinal vein (arrow) is present on each CTM. The characteristics of each patient/CTM are summarized in Table 2. Note that the hyperdense paraspinal vein is better appreciated on consecutive images, as viewed electronically at a picture archiving and communication system (PACS).
