Abstract:
Objective To observe 18F-FDG PET/CT manifestations of vertebral aggressive hemangioma.Methods Totally 24 patients with vertebral aggressive hemangioma were retrospectively enrolled,including 6 cases with lesions in cervical vertebrae,14 cases in thoracic vertebrae and 4 cases in lumbar vertebrae.18F-FDG PET/CT characteristics of lesions were observed,and the maximum standard uptake value(SUVmax)of lesions were compared among lesions with different CT performances.Results Among 24 cases,the lesion limited in vertebral body in 5 cases(5/24,20.83％)but affected vertebral body and appendages in 19 cases(19/24,79.17％).Accompanied vertebral osteolytic destruction and internal residual bone were noticed in 10 cases(10/24,41.67％),simple osteolytic destruction was found in 6 cases(6/24,25.00％),thickened and sparse trabeculae was observed in 4 cases(4/24,16.67％),while 4 cases(4/24,16.67％)without significant bone abnormalities.Compared to adjacent non diseased vertebrae,the radioactive uptake of lesions increased in 12 cases(12/24,50.00％),approached in 9 cases(9/24,37.50％)and decreased in 3 cases(3/24,12.50％).Uniform distribution of radioactivity was noticed in 14 cases(14/24,58.33％),while uneven distribution of radioactivity was found in 10 cases(10/24,41.67％).No significant difference of SUVmax was found between hemangioma lesions(2.50[1.53,4.13])and liver tissue(2.79±0.53)(Z=0.261,P=0.794).SUVmax of lesions with cortical bone destruction was higher than that of those without destruction(P＜0.05),of those with fractures was higher than lesions without fractures(P＜0.05).Conclusion Vertebral aggressive hemangioma had diverse CT manifestations,with 18F-FDG metabolism similar to liver.Vertebral aggressive hemangioma with cortical bone destruction and fractures had higher metabolism.
