Abstract:
BACKGROUND:Pathological examination and MRI have been widely used in clinic, but their combination is rarely reported in discrimination of early spine infections.
OBJECTIVE:To determine the accuracy of pathology and MRI for discrimination between early pyogenic spondylitis and brucella spondylitis.
METHODS:Twenty-two patients with pyogenic spondylitis and 20 patients with brucella spondylitis who had CT-guided percutaneous biopsy and MRI of the spine were retrospectively reviewed. Pathological observations included structure and activity of bone lesions, tissue cells and their main components;MRI observations included signal and sign changes at lesion sites. Statistical analysis was performed with the chi-square test.
RESULTS AND CONCLUSION:The patients with pyogenic spondylitis had a significantly higher incidence of pathological and MRI findings as fol ows (P<0.05):neutrophil infiltration;intervertebral disc abnormal signal, location of vertebral body lesions anterior+posterior, obviously shape change in the vertebral body, paraspinal abnormal signal, presence of intraosseous or paraspinal abscess. Pathological and MRI examination was accurate for early differentiation of pyogenic spondylitis from brucella spondylitis.
