Fig. 2. Magnetic resonance images (MRIs) on postoperative day 14. Sagittal T1- and T2-weighted MRIs show that the hematoma still exists from the Th6 to the Th9 level, but it is smaller than it was on postoperative day 3, and compression of the spinal cord has disappeared. Arrows indicate the hematoma at the Th7 level in axial and sagittal MRIs.
