32例肾上腺血肿多层螺旋CT诊断分析

目的探讨肾上腺血肿的多层螺旋CT(MSCT)征象及其诊断价值。方法回顾性分析经手术或CT随访证实的32例患者的CT资料,采用MSCT机平扫及增强扫描。结果 32例患者中,单纯右侧肾上腺血肿21例(65.6%),单纯左侧8例(25.0%),双侧3例(9.4%);外伤23例(71.9%),非外伤9例(28.1%);肾上腺圆形、类圆形高密度血肿24例(75.0%),肾上腺弥漫性出血5例(15.6%),肾上腺肿胀密度增高3例(9.4%)。动态增强三期扫描均未强化。结论多层螺旋CT能准确显示肾上腺血肿的大小、形态及密度,对肾上腺血肿的早期诊断及鉴别诊断具有重要意义。

Diagnosis of adrenal hematoma by multislice spiral CT: analysis of 32 cases

Objective To discuss the feature and diagnostic value of multislice spiral CT（MSCT） in adrenal hematoma.Methods A retrospective analysis was carried out in 32 cases with adrenal hematoma confirmed by surgery or follow-up CT,whose CT data were obtained from MSCT plain and enhanced scan.Results Out of 32 cases with adrenal hematoma,21 were found to have right adrenal hematoma（65.6%）,8 left adrenal hematoma（25.0%）,and 3 bilateral adrenal hematoma（9.4%）;23 cases were traumatic（71.9%） and 9 non-traumatic（28.1%）.Adrenal hematomas appeared as round or oval hyperdense mass in 24 cases（75.0%）.Diffuse irregular hemorrhage occurred in 5 cases（15.6%）,swollen gland with higher density in 3 cases（9.4%）.All images were not enhanced with three-phase contrast-enhanced dynamic scan.Conclusions MSCT scan can accurately demonstrate the size,shape and density of adrenal hematoma and is of great significance to its early diagnosis and differential diagnosis.
