Magnetic resonance image findings in pug dogs with thoracolumbar myelopathy and concurrent caudal articular process dysplasia

Table 1 Table summarising clinical and radiologic findings in Pug dogs with myelopathy apparently associated with caudal articular process (CAP) dysplasia. *SAD = spinal arachnoid diverticulum. **Vertebra affected (left/right) where a = aplastic, ‘h’ = hypoplastic and ‘n’ = normal
