Role of magnetic resonance imaging in evaluation of tubercular spondylitis: pattern of disease in 100 patients with review of literature.
ABSTRACT The purpose of this study is to evaluate the role of magnetic resonance imaging (MRI) in evaluation of tubercular spondylitis and to correlate imaging findings with clinical severity of the disease.
One hundred consecutive patients, who presented with features suggestive of spinal infections, were subjected to MRI examination. T1W and STIR images were obtained followed by T2W and post-contrast T1W images. Various imaging characteristics of spinal infections were noted and correlated with the clinical severity of the disease.
Backache was the most common presenting symptom present in 86 %, while paraparesis was the most common sign seen in 62 %. The neurological status of the patients correlated well with MRI findings in the majority of the cases with an overall good correlation obtained in 96 % of cases. The majority of the vertebrae and intervertebral discs affected showed hypointensity or isointensity on T1W images and hyperintensity on T2W images. Epidural/dural disease was present in 74 % while 68 % of patients demonstrated decreased intervertebral disc height. Epidural extension and subligamentous spread was in 74 % and 90 % of patients respectively.
MRI plays a vital role in early and accurate diagnosis of spinal infections. It is non-invasive and clearly demonstrates soft tissue anatomy and pathology which makes it superior to X-rays and Computed Tomography (CT). Imaging findings of tubercular spondylitis were also found to have a good correlation with the clinical status of the patients. Hence, it is of much help in the evaluation and assessment of patients presenting with features of spinal infections.

ABSTRACT: Spinal cord/nerve root compression secondary to a tubercular epidural abscess leads to neurological deficit. Depending on the extent and duration of compression, the end result after treatment may vary from complete recovery to permanent deficit. ASIA has been used extensively to correlate between MRI and neurological status due to traumatic spine injuries. MRI has stood as an invaluable diagnostic tool out of the entire range of current imaging modalities. However, inspite of considerable literature on the applications of MRI in spinal tuberculosis, there have been few studies to assess the relationship between the MRI findings and the neurological deficit as assessed by clinical examination.Indian Journal of Orthopaedics 07/2014; 48(4):366-73.

ABSTRACT: Spinal tuberculosis presents in various pathological patterns. The clinical presentation and often the management depend on exact pathological findings. Objective of study was to evaluate the Pathology of spinal tuberculosis as depicted by MRI findings in 119 consecutive cases of spinal TB.Methodology: It was a cross sectional and observational study conducted at Civil Hospital, Karachi from July 2010 to December 2012.Total numbers of participants were 119. Diagnosis was based on positive histopathology results along with the supportive evidence in MRI. A pre-structured questionnaire was constructed to record the data. Study was ethically approved by Institutional Review Board of Dow University of Health Sciences. Sample size was calculated by using Open-EPI software. All the data was entered and analyzed through SPSS 19.Result: There were 119 patients who participated in this study out of which 52 were males and 67 were females. Most common level was Dorso-lumbar (33.6%) and 87.5% of them had spondylodiscitis while 90% had cord compression. All 6 (100%) patients who had their upper- dorsal region affected had gibbus formation while all those patients having lumbosacral region involved had thecal compression 4 (100%). Most common mode of treatment used in patients having Spinal TB at Lumbar region was conservative (86.2%). MRI findings were mostly shadowed with features such as disc destruction and thecal or cord compression. MRI scan could be used for early detection of spinal TB which can reduce disability and deaths in patients. Major clinical findings in spinal TB were fever, Para paresis and back pain.International Archives of Medicine 03/2014; 7(1):12. DOI:10.1186/1755-7682-7-12 · 1.08 Impact Factor
