MRI Findings in a Dog with Unilateral Sacroiliitis

Abstract

Sacroiliitis is a rare pathology recently reported in the veterinary literature, mainly in large-breed dogs. The main associated clinical signs are lumbosacral pain and/or lameness of one or both hindlimbs. However, it is a nonspecific presentation and can be mistaken for other clinical disorders with a higher prevalence, such as caudal lumbar disc herniation or degenerative lumbosacral stenosis, among others. The present report describes the MRI findings in a German shepherd dog with unilateral sacroiliitis secondary to a possible trauma and the relevance of advanced imaging techniques in these patients.
