Summary
Infectious sacroiliitis diagnosis relies heavily on imaging due to non-specific clinical signs. Advanced techniques like CT and MRI are crucial for detecting subtle bone and soft tissue lesions.
Area of Science:
- Radiology
- Infectious Diseases
- Orthopedics
Background:
- Infectious sacroiliitis presents with non-specific clinical and biological findings.
- Acute and subacute cases may be associated with other arthritic conditions and soft tissue lesions.
Purpose of the Study:
- To discuss the clinical, biological, and radiological findings in infectious sacroiliitis.
- To evaluate the utility of various imaging modalities for diagnosing infectious sacroiliitis.
Main Methods:
- Review of 11 cases of infectious sacroiliitis.
- Analysis of clinical, biological, and radiological data.
- Comparison of radiography, bone scintigraphy, tomography, computed tomography (CT), and magnetic resonance imaging (MRI).
Main Results:
- Radiography reveals advanced osteoarticular remodeling but often misses subtle lesions.
- Bone scintigraphy shows focal hyper-captation but lacks specificity.
- Tomography and CT effectively identify erosions and guide diagnostic punctures.
- MRI demonstrates bone marrow edema and excels in visualizing soft tissue lesions.
Conclusions:
- Radiological investigations are essential for diagnosing infectious sacroiliitis.
- CT is valuable for detecting erosions and guiding biopsies.
- MRI is a promising technique for its ability to detect bone marrow edema and soft tissue abnormalities.
