Abstract:
Objective To explore the imaging differences of vertebral multiple myeloma(VMM)and vertebral osteolytic metastasis on CT. Methods Review the imaging signs of 32 patients with VMM and 52 patients with vertebral osteolytic metastasis,then record and finally statistical analysis was carried out.Results Compare to 1 67 vertebras involved in 52 cases of vertebral metastasis,the patents with VMM had 220 vertebras involved.The incidence of the multiple small circular type of bone destruction in VMM was 42.66%(93/218),which was higher than that in vertebral metastasis 0.00% (0/165)(χ2 =92.963,P =0.000).The incidence of the irregular shape type of bone destruction in VMM was 23.39% (5 1/218),while it was higher in patients with vertebral metastasis 45.45%(75/165)(χ2 =20.704,P=0.000).It was also found that the incidence of the fragmentary type of bone destruction and the involvement of the unilateral pedicle in VMM were lower than that in patients with vertebral metastasis 8.7% (19/218 )& 27.27% (45/165)(χ2 =23.238,P =0.000), 6.82% (1 5/220)& 1 7.96% (30/1 67)(χ2 =1 1.477,P =0.001).The incidence of the crest protrusion type of bone destruction in patients with VMM was 16.06% (35/218),however it was 9.10% (15/165)(χ2 =4.013,P =0.045)in vertebral osteolytic metastasis. Conclusion The imaging features of VMM and vertebral osteolytic metastasis had certain characteristic.And they can be differentiated from each other,combining with clinical traits.
