If you put contrast in a sialocele where does it go?

Study: The study is a retrospective, observational study that describes clinical and CT sialographic findings in a group of dogs with confirmed sialoceles. The aims of the study were to determine the sensitivity of CT sialography for detecting affected salivary glands using surgery as the reference standard and to determine interobserver agreement for CT sialographic assessments.

Methods: Dogs were included if they underwent a CT sialography study followed by surgical resection of the diseased gland(s) and histopathological analysis. CT sialography studies of dogs with surgically confirmed sialoceles (n = 22) were reviewed by a European College of Veterinary Diagnostic Imaging (ECVDI)-certified radiologist and an ECVDI resident. Interobserver agreement was calculated using Cohen’s kappa statistics. CT sialography results were compared to surgical findings to determine sensitivity.

Results: Contrast leakage was detected in 12 of 22 dogs (54.5%), with intrasialocele leakage being most frequently observed (7/12, 58.3%). There was substantial agreement (κ = 0.70) between reviewers identifying diseased glands, substantial agreement (κ = 0.62) on the diagnostic quality, and no to slight agreement (к = 0.13) in the detection of contrast leakage. The overall sensitivity of CT sialography to detect surgically confirmed diseased glands was 66.7% (95% confidence interval: 48.8-80.8).

Conclusion: These findings support the use of CT sialography as an adjunct diagnostic test for treatment planning in dogs with sialoceles.
