目的探讨彩色多普勒超声对肾上腺肿瘤的诊断价值。方法 2008年4月至2012年4月期间,我院诊治的307例肾上腺肿瘤患者,彩色多普勒超声检查肿瘤病灶的大小、形态、边界、内部回声,以及内部血流分布等特征,并与病理结果,进行对比分析。结果通过彩色多普勒超声检查,307例肾上腺肿瘤患者中,287例患者被诊断为肾上腺肿瘤,其检出率为93.5%,另外的15例漏诊,5例患者被误诊为肿大淋巴结。307例肾上腺肿瘤患者中,277例患者为良性肿瘤,30例患者为恶性肿瘤。彩色多普勒血流显像检查显示,良性肿瘤病灶形态规则,边界清晰,内部均为低回声(髓质脂肪瘤内部高回声),其余,病灶内部几乎没有血流信号;恶性肿瘤病灶形态不规则,边界不清,内部为混合性回声,病灶内部具有丰富的血流。结论对于肾上腺肿瘤患者,彩色多普勒超声无创性、准确地反应肿瘤病灶的特点,以及血流情况,为临床诊断提供客观的理论依据,值得临床推广。
Objective To investigate the diagnostic value of color Doppler ultrasound in adrenal tumors. Methods From April 2008 to April 2012, 307 patients with adrenal tumors diagnosed and treated in our hospital were examined by color Doppler sonography for the size, shape, boundary, internal echo and internal blood flow distribution of tumor lesions. Pathological results, comparative analysis. Results Of the 307 patients with adrenal tumors, 287 were diagnosed as adrenal tumors by color Doppler sonography. The detection rate was 93.5%. The other 15 patients were misdiagnosed and 5 patients were misdiagnosed as enlarged lymph nodes. Of 307 patients with adrenal tumors, 277 were benign and 30 were malignant. Color Doppler flow imaging showed benign tumor lesions morphology rules, the boundary is clear, the internal hypoechoic (medullary lipoma within the high echo), the rest of the lesion almost no blood flow signal; malignant tumor morphology is not Rules, the border is unclear, the internal hybrid echo, the lesion has a rich internal blood flow. Conclusion For patients with adrenal tumors, color Doppler ultrasound noninvasive, accurately reflect the characteristics of tumor lesions, and blood flow, provide an objective theoretical basis for clinical diagnosis, worthy of clinical promotion.
