脾淋巴瘤的超声诊断价值及其分型

Ultrasonic diagnostic value and classification of splenic lymphoma

目的探讨脾淋巴瘤的超声诊断价值及其分型。方法对31例脾淋巴瘤的临床资料、超声表现与病理进行对比分析，并行超声分型。结果31例脾淋巴瘤中，超声提示脾淋巴瘤3例，淋巴瘤脾累及5例，诊断正确率为25．8％。31例脾淋巴瘤超声表现可分为四型：①弥漫肿大型，占12．9％（4／31），肿大的脾内未见团块或结节；②粟粒结节型，占16．2％（5／31），脾内见大小不一的低回声结节（直径≤3cm）；③巨块型，占29．0％（9／31），肿块单发，直径大于3cm，伴或不伴中心坏死；④混合型，占41．9％（13／31），脾肿大，内可见大小不一的低回声结节与团块。结论超声对脾淋巴瘤的诊断有较高的临床价值，必要时可行超声引导下穿刺活检。

Objective To probe the ultrasonic diagnostic value in splenic lymphoma and classify the sonographic appearance of splenic lymphoma. Methods The clinical datas and ultrasonic appearances of 31 patients with splenic lymphoma were compared with the pathology. The ultrasonic images were classified. Results Among the 31cases,3 cases with splenic lymphoma and 5 cases with splenic infiltration of splenic lymphoma were correctly diagnosed by ultrasound. The diagnostic correct rate was 25.8%. The sonographic appearances of 31 cases were divided into four types. Homogeneous splenomegaly type（12.9%,4/31 ）, showed homogeneous splenomegaly without mass in the spleen. Multiple nodule type （16.2%, 5/31 ）, showed multiple hypoechoic nodules diffused in the spleen. Solitary mass type （29. 0%, 9/31 ）, showed solitary mass larger than 3 cm with or without necrosis in the spleen. Comples type （41.9%, 13/31）, showed splenomegaly, hypoechoic masses and nodulars of different sizes in the spleen. Conclusions The sonographic diagnosis of splenic lymphoma is valuable to the clinic. The ultrasound guided splenic biopsy could be carry out if necessary.
