Magnetic resonance imaging of tuberculous spinal infection
1Department of Diagnostic Radiology and Organ Imaging, United Christian Hospital, Kowloon, Hong Kong.
Abstract:
The magnetic resonance imaging (MRI) characteristics of 15 cases of tuberculous (TB) spinal infection were reviewed. The commonest site was the lumbar spine (53.3%), often with three or more contiguous vertebrae involved (47%). Destruction of the vertebral body and the presence of paraspinal soft-tissue masses were noted in 73.3%. Posterior element abnormalities, which is a significant finding, were seen in 40%, a slightly lower incidence rate than in other reported series. Epidural disease (53.3%) and disc abnormalities (73%) were more frequent than was realized. The role of intravenous contrast is discussed. Intravenous gadolinium is useful because it increases diagnostic confidence by characterizing and delineating the disease process, detects reactivation in old and healed TB, helps in treatment management and may prove valuable in monitoring therapy. Magnetic resonance imaging should be considered to be the imaging modality of choice for patients with suspected tuberculous spinal infection.
Insights
Magnetic resonance imaging (MRI) is the top choice for diagnosing spinal tuberculosis (TB). This study highlights common MRI findings in TB spinal infections, aiding in diagnosis and treatment.
Area of Science:
- Radiology
- Infectious Diseases
- Orthopedics
Background:
- Spinal tuberculosis (TB) is a significant global health concern.
- Accurate imaging is crucial for diagnosis and management of spinal TB.
- Magnetic resonance imaging (MRI) offers detailed visualization of spinal structures.
Purpose of the Study:
- To review the MRI characteristics of tuberculous spinal infection.
- To identify common patterns and key imaging findings.
- To evaluate the utility of contrast-enhanced MRI in TB spinal disease.
Main Methods:
- Retrospective review of 15 tuberculous spinal infection cases.
- Analysis of MRI findings, including location, vertebral involvement, and associated abnormalities.
- Assessment of the role of intravenous gadolinium contrast.
Main Results:
- Lumbar spine is the most common site (53.3%), often affecting multiple vertebrae.
- Vertebral body destruction and paraspinal masses are frequent (73.3%).
- Epidural disease (53.3%) and disc abnormalities (73%) are more common than previously thought.
Conclusions:
- MRI is the imaging modality of choice for suspected spinal TB.
- Contrast-enhanced MRI aids in diagnosis, detects reactivation, and monitors treatment.
- Understanding MRI patterns improves diagnostic confidence and patient management.
