Abstract

Abstract:

Objective To explore the different imaging characteristics of multi-segment brucella spondylitis (BS) and spinal tuberculosis (ST) in magnetic resonance imaging (MRI), so as to improve the level of early diagnosis and differential diagnosis. Methods Retrospective analysis was performed in 33 patients with multi-segment BS and 30 patients with multi-segment ST, who were diagnosed clinically or pathologically. Lesion location, vertebral body shape, surrounding tissues,and accompanying signs were studied according the different manifestations on MRI. Results The proportion of vertebral morphology, intervertebral disc involvement, kyphosis, sequestrum and calcification, paravertebral abscess were significantly different between the patients with multi-segmental BS and the patients with multi-segmental ST (P<0.05). Conclusion MRI findings of multi-segment BS and ST are different, MRI is helpful in differential diagnosis.
