Abstract:
Objective To evaluate the value of imaging investigations in the diagnosis of bone echinococcosis by analysing the X-ray,CT and MRI signs.Methods Imaging data of 7 patients aged from 23 to 56 years(mean age 39.5 years)with bone echinococcosis were analysed retrospectively.All cases underwent X-ray plain film examination(frontal view and lateral view);4 cases were examined with CT; 3 cases received MRI scan.Results The echinococcosis located in skull(1 case),vertebrae(3 cases), sacrum(1 case),ilium(1 case)and ribs(1 case)respectively.X-ray signs:5 cases appeared as expanding destructive lesion,two of them were solitary cystic lesions,the others were multiple cystic lesions. Lytic destruction was showed in 2 cases.Sclerotic margin,calcification,soft tissue mass was visible in 5, 1 and 4 cases respectively.CT signs:3 of 4 cases were expanding destructive lesions,including 2 multiple cystic lesions and 1 solitary cystic destruction.The other one showed lytic destruction.3 had sclerotic margin;calcification was identified in 2 cases,4 cases accompanied with soft tissue mass.MRI signs:All of 3 cases occurred at vertebrae,solitary cystic lesion in one and multiple cystic lesions in two.Lesions showed low signal on T_1 WI image,high signal on T_2 WI image and appeared as grape shapes.Involved vertebrae showed wedge-shaped.Conclusion Imaging modalities were significantly valuable in the diagnosis of bone echinococcosis.Combination of X-ray radiography,CT,MRI and epidemiological information is helpful in the diagnosis and differential diagnosis of the bone echinococcosis.
