彩色多普勒超声诊断恶性淋巴瘤结外浸润的价值

The value of color doppler sonographic diagnosis for extranodular invasion of malignant lymphoma

目的 :探讨彩色多普勒超声对恶性淋巴瘤结外浸润的诊断价值。方法 :回顾性分析 1995年以来经超声引导穿刺活检病理证实的结内恶性淋巴瘤结外浸润 5 8例的二维及彩色多普勒超声表现及特征 ,3 3例同期进行了CT检查。结果 :结内恶性淋巴瘤结外最易受侵的脏器为脾脏 ,其次是肝脏、肾脏及睾丸等。本组脾脏浸润 42例 ,占 72 .41% ;肝脏受侵14例 ,占 2 4.14% ;肾脏受侵 5例 ,占 8.62 %。声像图主要特征为受累脏器弥漫或局限分布的低回声结节和血流信号的增多。依据声像图特点 ,可分为两型四种声像图表现。本组Ⅰ型 12例 ;Ⅱ型 46例。结论 :彩色多普勒超声对结内恶性淋巴瘤结外浸润的检查无创无痛、方便快捷、结果可靠 。

Objective:To explore the value of color Doppler ultrasound diagnosis for extranodulor invasion of malignant lymphoma(EIML).Methods:The sonographic appearance of 58 patients with EIML confirmed by ultrasound-guided biopsy,postoperation pathology were analysed retrospectively,compared with CT.Results:The most susceptible locations were spleen,secondly,liver,kidney,and testicle etc.In this group,spleen was influenced in 42 cases(72.4%),and the main characteristic of lesions in sonography were local or diffuse hypoechoic echogenicity with increased flow signal in the lesion.According to characteristic of sonographic appearance,the disease can be divided into two types,diffusion type and nodule type,with four kinds of sonographic appearances.In this group,type I included 12 cases,and type Ⅱ 46 cases.Conclusion:Sonography can be used as better method to diagnose extranodulor invasion of malignant lymphoma.
