Abstract

Objective To provide some references for diagnosing and treating the lymphoma in abdominal lymph nodes summarizing its sonographic features.Methods The clinical data and sonographic findings of 50 lymphoma patients with original appearance of abdominal mass or lymphadencetasis were retrospectively collected and analyzed from September,2010 to December,2013.Results Among the 50 cases,24 had abdominal distension and pain,4 swell of lower limbs,5 low back pain,4 diarrhea,12 superficial lymph node enlargement,and 11 body mass loss over 10％ within 6 months,night sweating,and an over 38℃ fever for 3 days.According to AnnArbor staging,there were 4 cases of stage 1,5 stage Ⅱ,12 stage Ⅲ,26 stage Ⅳ,and 3 no stage.Laboratory tests showed that β 2-microglobulin increased in 16 cases,lactate dehydrogenase increased in 21 cases,erythrocyte sedimentation rate got faster in 15 cases,tuberculin test was positive in 3 cases.Single package block type accounted for 34.0％ (17/50).The giant mass of 11 cases was over 10 cm.The mass position of the 17 cases of single block type located in retroperitoneal and mesenteric root.Conclusions Ultrasonography is helpful for early diagnosing the lymphoma in abdominal lymph nodes and can provide some references for its diagnosis and treatment.
