13y MC Miniature Dachshund with progressive neurologic deficits of 10 days duration. The dog became acutely worse and now has
marked tetraparesis. Images d and e are at the level of the C5–6 intervertebral disk. The C5–6 intervertebral disk space is narrow
(a–c: arrow). Mildly T1 and T2 hypointense extruded disk material (b–e: arrowhead) compresses and displaces the spinal cord
dorsally. Ventral slot decompression surgery was performed at C5–6, and partially mineralized disk material was removed from the
ventral extradural space.
