Magnetic resonance imaging (MRI) demonstrated a massive ventral spinal subdural hematoma from T12 to S1 (Figure 1).
Operative microscope views of the dorsal thoracolumbar spinal dura. Note the mottled appearance of the dural sac (a). Opening of the dural sac (b, c) demonstrates thick clotted blood intradurally. The massive volume of the subdural blood has filled the intradural space and obliterated all egress of cerebrospinal fluid (d).
