目的探讨弥漫性淋巴管瘤病(disseminated lymphangiomatosis,DL)的临床及CT表现特点。方法回顾性分析4例经临床病理证实的DL的临床及CT资料。结果 4例均累及脾脏,CT平扫表现为脾实质内多发类圆形、分叶状囊性低密度影,部分病灶内可见间隔,增强扫描囊壁轻度强化,间隔增强后静脉期轻~中度强化3例,延迟期轻度强化2例;1例累及肝脏,囊壁轻度强化;腹部脏器外单囊、多囊性病变各1例,多囊性病变间隔轻度强化;2例分别累及腹膜后和纵隔,病变沿组织间隙生长,呈塑形改变;1例累及胸骨、多发胸椎及肋骨,为多发大小不等的低密度影,部分病灶边缘骨质轻度硬化,增强扫描病灶无强化。结论 DL的CT表现具有一定的特征性,CT检查可确定病变的范围及数目。
Objective To investigate the clinical and CT features of disseminated lymphangiomatosis (DL). Methods Retrospective analysis of 4 cases of clinically and pathologically confirmed DL clinical and CT data. Results All 4 cases were involved in the spleen. CT showed multiple round and lobulated cystic low density lesions in the splenic parenchyma. Some of the lesions could be seen in the cysts. The enhancement of the cyst wall was mild and the venous phase was enhanced ~ Moderate enhancement in 3 cases, mild delayed enhancement in 2 cases; 1 case involving the liver, mild enhancement of the cystic wall; 1 case of single cystic and cystic lesions outside the abdominal organs, with slight cystic cystic lesion strengthening; 2 Cases involving the retroperitoneum and mediastinum, lesions along the tissue gap growth, shape changes; 1 case involving the sternum, multiple thoracic and ribs, multiple lesions of varying sizes of low density, partial lesion edge of bone mild sclerosis, enhanced scan No enhancement of the lesion. Conclusion The CT findings of DL have certain characteristics. CT examination can determine the scope and number of lesions.
