成人原发腹部淋巴管瘤超声表现

Ultrasonographic Characteristics of Adult Primary Abdominal Lymphangioma

目的探讨成人原发腹部淋巴管瘤(APAL)的超声诊断价值。资料与方法回顾性分析12例APAL(海绵状淋巴管瘤1例,囊性淋巴管瘤11例)的声像图表现,并与CT血管造影(CTA)和MRI对照。结果 12例APAL患者中,4例发生于脾脏,3例起源于肠系膜,5例位于腹膜后。脾内和肠系膜淋巴管瘤中5例为圆形或浅分叶状,腹膜后5例占位形态不规则。多发多房者3例,单发多房者4例,单发单房者5例。超声显示,囊壁血流3例,2例显示分隔血流。超声提示淋巴管瘤2例,误诊为转移瘤及脂肪瘤各1例,1例肠系膜病变误诊为腹膜后占位。结论成人腹部原发淋巴管瘤的典型表现为多房分隔,超声具有一定的诊断意义。

Purpose To investigate the value of ultrasound in diagnosing adult primary abdominal lymphangioma（APAL）.Materials and Methods The sonography manifestations of 12 adult patients with abdominal lymphangioma（1 cavernous lymphangioma,11 cystic lymphangioma） were retrospectively analyzed,and the results were compared with MRI and CTA.Results 4 cases were originated from spleen,while 3 from mesentery,5 from retroperitoneum.The shape of 5 tumors in the spleen and mesentery was rounded or lobulated,and 5 retroperitoneal mass were irregular.3 cases were multiple multilocular,4 cases were solitary multilocular,5 cases were solitary unilocular.Ultrasound showed blood flow within the wall in 3 cases,and within the septations in 2 cases.Ultrasonography identified 2 cases as lymphangioma.2 cases were misdiagnosed as metastatic tumors and lipoma respectively.1 mesenteric lymphangioma was diagnosed as retroperitoneal tumor.Conclusion Adult primary abdominal lymphangioma is typically shown as multiloculated with septations.Ultrasound is valuable in the clinical diagnosis.
