四肢淋巴管瘤的影像学与病理对照

The Comparative Study of Pathology and Imaging in Limbs Lymphangioma

目的探讨四肢淋巴管瘤的CT、MRI表现及病理改变,旨在提高对其认识。资料与方法搜集经手术病理证实的20例四肢淋巴管瘤患者的影像资料,4例行CT检查,19例行MRI检查,其中2例行MRI增强扫描。分析其影像学表现,并与病理结果对照。结果囊性淋巴管瘤4例,表现为单房或多房分叶状囊性肿物;海绵状淋巴管瘤12例,表现为皮下软组织增厚,呈"网格"样改变,可见多发扩张淋巴管;血管淋巴管瘤4例,表现为多房囊腔,周围可见增粗迂曲血管,淋巴管囊内出血可见液-液平面。结论影像学检查对四肢淋巴管瘤的诊断具有重要价值,其中MRI较CT更具优势。

Objective To discuss the CT,MRI and pathological appearance of limbs lymphangioma,in order to improve its recognition.Materials and Methods 20 cases with histologically confirmed lymphangioma were collected and retrospectively analyzed.CT scan were performed in 4 cases,and MR scan in 19 cases,enhanced MR scan in 2 cases.Imaging findings were analyzed compared with pathological results.Results The cystic lymphangioma（n=4） had uni or multilocular cystic masses;The cavernous lymphangioma （n=12）showed lattice change with many dilated lymphatic channel;the hemolymphangioma（n=4） showed multilocular cyst,the dilating and tortuous vessels were seen around the cyst,there was liquid-liquid surface in lymphangioma with hemorrhage.Conclusion Imaging examination is very useful in diagnosis of lymphangioma,MRI is superior than CT.
