Figure 3From: Spinal dural ossification causing neurological signs in a catTransversal planes of magnetic resonance images before surgery (A, B, C, D, E, F) and after surgery (G, H, I, J, K, L) . The symbols in the right upper corner encode images taken at the level of the third cervical vertebra (C3), the fourth cervical vertebra (C4) and the fifth cervical vertebra (C5). Intradural extramedullary/ extradural hypointensity (pointer arrows) in T1W (t1) and T2W (t2) is causing ventrodorsal spinal cord flattening and compression. The asterisk shows post operative scar tissue, the arrows show the ventral sinuses.Back to article page
