case_images: a Lateral dynamic myelographic image demonstrating the site of CSF leakage at T7/T8 (white arrow), with contrast medium observed spreading within epidural space (white arrow heads) from subarachnoid space (black arrowheads). b. Lateral CT myelographic image at T7/T8 demonstrating a partially calcified disc (white arrow). c. Axial CT myelographic image at T7/8 level demonstrating a collection of ventral epidural fluid (black dotted circle) and a partially calcified disc (white arrow)

case_images: Dynamic myelography demonstrated the leakage of contrast medium into the ventral epidural space from the subarachnoid space at the T7/T8 intervertebral level (Fig. 1a). By reviewing images from both CT and dynamic myelography, we suspected that the sharply protruding calcified intervertebral disc had ruptured the ventral side of the dura mater, allowing for CSF to leak through the tear into the ventral epidural space (Fig. 1b, c).
