Diagnostic Imaging of Discospondylitis

Area of Science:

• Veterinary Medicine
• Diagnostic Imaging
• Infectious Diseases

Background:

• Discospondylitis is a spinal infection affecting dogs and cats of all ages and breeds.
• While radiography is standard, it may not always provide early or comprehensive diagnostic information.
• The variety of causative agents necessitates accurate etiological identification for successful treatment.

Purpose of the Study:

• To highlight the benefits of advanced imaging modalities (CT and MRI) in diagnosing discospondylitis.
• To emphasize the importance of imaging the entire spine due to potential multifocal involvement.
• To discuss the role of various diagnostic methods, including biopsy, in identifying causative agents.

Main Methods:

• Review of current diagnostic approaches for discospondylitis.
• Comparison of radiography with advanced imaging techniques like computed tomography (CT) and magnetic resonance imaging (MRI).
• Discussion of diagnostic procedures including blood/urine cultures, Brucella canis screening, and image-guided biopsy.

Main Results:

• Advanced imaging (CT/MRI) offers advantages over radiography, enabling earlier diagnosis and detection of concurrent diseases.
• Imaging the entire spine is recommended due to the possibility of discospondylitis affecting multiple intervertebral disk spaces.
• Accurate identification of causative agents is essential for effective treatment protocols.

Conclusions:

• CT and MRI are valuable tools for the early and comprehensive diagnosis of canine and feline discospondylitis.
• A thorough diagnostic workup, potentially including image-guided biopsy, is critical for identifying the specific cause and guiding treatment.
• Successful management of discospondylitis relies on prompt and accurate etiological diagnosis.
