Compressive spinal cord injury caused distal hematoma far away from the lesion site. (A) A segment of rat spinal cord taken out immediately after compression. Aster shows the compressive point, and the arrow shows the distal hematoma which could be seen grossly. (B-D) H-E staining of the spinal cord sections indicated blood in the compressive lesion center and far-away hematoma which forms spindle-shaped foci at 6 h, 3 days, and 14 d post injury, respectively. (E-G) Higher magnification of the boxes in the pictures above accordingly. Note that cavity formed from the hematoma at 14 days post injury. Bar = 1 mm (A-D), 200 μm (E-G).
