A 44-year-old woman comes to her physician and complains of headache and backache. On examination, she is found to have fluid accumulated in the spinal epidural space because of damage to blood vessels or meninges. Which of the following structures is most likely ruptured?

The Internal Veebral Venous Plexus is located in the spinal epidural space. The veebral aery and vein occupy the transverse foramina of the upper six cervical veebrae. The external veebral venous plexus consists of the anterior pa, which lies in front of the veebral column, and the posterior pa, which lies on the veebral arch. The lumbar cistern is the enlargement of the subarachnoid space between the inferior end of the spinal cord and the inferior end of the subarachnoid space.
