Magnetic resonance imaging (MRI) was used in 13 patients with peripheral lymphedema and 2 patients with extensive cavernous lymphangioma of the limb for the purpose of evaluating its role in diagnosis of lymphatic disorders. In chronic lymphedema, MRI showed deformity of lymphatics at different tissue levels. In the subcutis, MRI characteristically displayed diffuse edema or a honeycombed pattern consistent with reticular lymphangiectasis and "lakes" with a marked increase in signal intensity with T2-weighted imaging. In lymphedema hyperplasia and chylous reflux, MRI depicted dilated retroperitoneal lymphatic collectors and lumbar trunks. In cavernous lymphangiomatosis, MRI demonstrated a prominent lattice-like pattern which had lower signal intensity on T1-weighted imaging and higher intensity on T2-weighted imaging. The findings of MRI are valuable not only for accurate assessment of lymphatic dysplasia syndromes but also provide a blueprint for treatment options.
对13例周围性淋巴水肿患者和2例肢体广泛性海绵状淋巴管瘤患者进行了磁共振成像（MRI）检查，以评估其在淋巴系统疾病诊断中的作用。在慢性淋巴水肿中，MRI显示不同组织层面淋巴管的畸形。在皮下组织，MRI特征性地表现为弥漫性水肿或呈蜂窝状，与网状淋巴管扩张一致，且在T2加权成像上可见信号强度显著增加的“湖”。在淋巴水肿增生和乳糜反流时，MRI显示腹膜后淋巴管收集器和腰干扩张。在海绵状淋巴管瘤病中，MRI表现为显著的网格状，在T1加权成像上信号强度较低，在T2加权成像上信号强度较高。MRI检查结果不仅对准确评估淋巴发育异常综合征有价值，还为治疗方案提供了蓝本。
