Abstract:
Objective To observe imaging manifestations of spinal chronic osteomyelitis.Methods Totally 56 patients with spinal chronic osteomyelitis were retrospectively enrolled,including 18 cases complicated with synovitis,acne,pustulosis,hyperostosis and osteomyelitis(SAPHO)syndrome while 38 cases did not.CT and MRI manifestations were observed.Results Among 56 cases,cervical spine involvement was observed in in 25 cases(25/56,44.64％).Single spine segment involvement,2 segments involvements and 3 or more segments involvements were found in 17(17/56,30.36％),18(18/56,32.14％)and 21 cases(21/56,37.50％),respectively.The ratio of 3 or more segments involvements in 18 cases with SAPHO syndrome was 61.11％(11/18),while in 38 cases without SAPHO syndrome was 26.32％(10/38),the former was higher than the latter(P＜0.05).Meanwhile,16 cases(16/56,28.57％)complicated with compression fracture,30(30/56,53.57％)with hyperosteogeny,22(22/56,39.29％)with paraspinal soft tissue swelled and 15(15/56,26.79％)with extra spinal involvements.The ratio of extra spinal involvement in patients with and without SAPHO syndrome was 72.22％(13/18)and 5.26％(2/38),respectively,the former was higher than the latter(P＜0.05).Conclusion Imaging manifestations of spinal chronic osteomyelitis had certain characteristics.In patients complicated with SAPHO syndrome,3 or more segments of spine involvements were common,with more extra spinal involvements.
