Objectives:
Recently, CT gained influence in the diagnosis of upper limb and axial skeleton pathologies. Based on the clinical caseload, this study presents different cases of pathologies associated with the pelvic and lumbar area in the horse and demonstrates the technique and positioning during image acquisition. The value of CT-based diagnosis is presented in comparison to basic imaging modalities.
Methods:
Medical records and radiology reports of 12 horses undergoing CT for suspicions of pelvic or lumbar pathology at Caesars Equine Specialty Hospital over 18 months were collected and evaluated via a Canon Aquilion CT scanner TSX-201A.
Results:
Two horses were diagnosed with lumbar vertebral fractures and another two animals had coxofemoral joint arthritis and a weanling marked bilateral coxofemoral joint OCD. Four horses were diagnosed with fractures of the pelvic area, three were involving the acetabulum and one was a fracture of the ilium. One horse showed marked unilateral SI-pathologies. A pony was scanned within 12 months of FHO surgery and one horse underwent a CT examination for evaluation of the invasiveness of a preputial tumor. Neither case was able to have a proven pre-CT diagnosis, allowing judgment and decision making, given the anatomic area of interest.
Conclusions:
This report shows the importance and feasibility of CT for diagnosing pelvic and lumbar area pathology highlighting the potential and significance of cross-sectional imaging in equine orthopedics. Speed of CT, acquisition of raw data, and the ability of post-acquisition processing present significant advantages in an anatomic area where osseous and soft tissue-on-bone pathologies dominate the differential diagnostic list.
