Abstract
Objective To summarize the SPECT/CT manifestation of spondylitis caused by Brucells infection and to evaluate the diagnostic value. Methods From June 2012 to October 2015, a total of 28 patients (14 males, 14 females, average age 46.4 years) with Brucellosis spondylitis confirmed by laboratory test and pathology were included. The images of whole-body bone scan and SPECT/CT fusion imaging were retrospectively analyzed. According to the pathological and serologic test results, the diagnostic efficacy of imaging was calculated. χ2 test was used. Results Most of the Brucellosis spondylitis happened in the lumbar(76.7%, 43/56), and the most common locations were L3, L4, L5 (72.1%, 31/43). Two or more involved consecutive vertebra were found in 71.4%(20/28) of the patients. Moderate radioactive distribution was showed in 89.2%( 50/56) of lesions, high radioactive distribution was showed in 5.4%(3/56) of lesions, and mild radioactive distribution was showed in the rest 3 lesions. Thirty-three lesions(58.9%, 33/56) had diffuse increased radioactivity uptake in the affected vertebra, and 32.1%(18/56) showed diffuse increased radioactivity at the superior and inferior margin of the vertebra; only 8.9%(5/56) of lesions were on one side of the vertebral bodies. The SPECT/CT results were as follows: (1) Bone destruction was showed in 80.4%(45/56) of lesions, and the edge of the lesion was clear. (2) For 66.7%(30/45) of lesions, bone hyperplasia was seen along with bone destruction and moderate radioactivity concentration on the edge of destruction area. (3) The damage of the intervertebral disc was mild, and the vertebral abscess was relatively rare (5.4%, 3/56). The diagnostic accuracy of SPECT/CT was statistically higher than that of whole-body bone scan: 67.8%(38/56) vs 96.2%(54/56); χ2=13.1, P<0.05. Conclusion SPECT/CT imaging has a higher diagnostic efficiency than whole-body bone scan in Brucellosis spondylitis.
