[Abstract] Objective: To analyse MRI findings of brucellosis spondylitis(BS) and to improve the knowledge and diagnosis of this disease.Materials and Methods: The clinical date and MRI of 13 cases with clinically or histopathologically proved BS were retrospectively analysed.Results: Of 13 patients with BS, the adjacent vertebral body involved in 12 cases. BS mainly affected the lumber spine, mostly the L4. MRI findings included: Morphology of vertebral body showed no obvious change. Two cases showed marrow oedema only with no obvious bone destruction. Bone destruction were detected in 11 cases, which was small and multiple and was often focaled with the edge of vertebral body. Abnormal vertebral body showed homogeneous or heterogeneous hypointensity on T1WI and heterogeneous hyperintensity on STIR, and heterogeneous enhancement on enhanced scan. Bone destruction was accompanied by marrow oedema and osteosclerosis. Eight cases showed obvious osterphyte in the rim of vertebral body. Twelve cases showed disc involvement, intervertebral space was often normal or slightly narrowed. Paraspinal soft tissue swelling was shown in 13 cases, in which paraspinal abscess was formed in 3 cases and epidural abscess in 2 cases. The abscess was small with thick and irregular enhanced wall on enhanced scan.Conclusions: MRI of BS shows certain characteristics, which are helpful in diagnosis and differential diagnosis of this disease.
