The value of multi-slice spiral CT in the diagnosis of carotid body tumor

Objective:To discuss the value of MSCT findings in the diagnosis of carotid bodytumor.Methods:13 cases with carotid body tumor by 16 MSCT enhanced CT scan were analyzed respectively.The shape,in and out vessels of angioma,relation between the angioma and encephalic structure were observed.The MSCT findings were analyzed retrospectively in comparison with operative findings of carotid body tumor.Results:Thirteen cases were all located at the level of carotid artery bifurcation.All lesions demonstrated well-marginated masses of homogeneous softtissue.All cases were manifested as early obvious homogeneous or inhomogeneous enhancement,in which supplying and drainage vessels were displayed in 3 cases.The angle of the common carotid bifurcation was enlarged.7,5,1 of 13 carotid body tumors were classified as shamblin Ⅰ,shamblin Ⅱ and shamblin Ⅲ type,respechvely.The diagnosis of MSCT was confirmed by post-operation pathological sections.The accuracy rate was 100%.Conclusion:MSCT and post-processing technique have advantage in showing the shape,location,relation between the angioma and encephalic structure,MSCT can not only support the diagnosis,but also provide clinical classification for surgical plan.
