“…This made it difficult to conclude a clear relationship between the presence of a specific vertebral condition and the conformation of SAD. Recently, it has been shown that MRI has a fair sensitivity for the identification of CAP dysplasia, particularly if using three‐dimensionally reconstructable volumetric interpolated breath‐hold examination (VIBE) sequences compared with traditional T2‐W 24 . Although CAP dysplasia was identified in some dogs in this study, given that CT is the gold standard for diagnosis of this condition and the VIBE sequence was not performed, this could have been missed.…”

The conformation of spinal arachnoid diverticula (SAD) and their clinical implications are poorly characterized in dogs. This retrospective cross‐sectional study describes different SAD conformations in dogs and aims to identify if there is an association between SAD conformation and clinical features, localization, syringomyelia (SM) presence, concurrent vertebral condition, treatment option, and short as well as long‐term outcome. Sixty‐two dogs were included (12 cervical and 50 thoracolumbar SAD). All dogs with a cervical SAD had a cranial tethered conformation and were not included in the statistical analysis. Half of the dogs with a thoracolumbar SAD were cranial tethered, and the other half were caudal tethered. SM associated with SAD had a moderate prevalence in the cervical region (58.3%) and a high prevalence in the thoracolumbar region (82%). All dogs with the presence of SM and caudal tethered SAD had a cranial positioned SM, and all dogs with SM and a cranial tethered SAD had a caudal positioned SM. The SM absolute length and SM length/L2 ratio were significantly higher (P = .018, respectively) in the caudal tethered SAD compared with the cranial tethered SAD. The short‐term outcome was statistically different (P = .045) between caudal and cranial tethered thoracolumbar SAD, but not the long‐term outcome (P = .062). Multivariable logistic regression identified thoracolumbar caudal tethered SAD conformation had a better short‐term outcome (P = 0.017, OR: 0.043, CI: 0.003–0.563), independently of SM length measurements. SAD conformation in dogs can influence SM formation. A possible link between short‐term outcome and SAD conformation was found, but further research is warranted.
