淋巴管瘤的CT影像学特征与临床病理分析

Analysis of CT imaging diagnosis of lymphangioma and clinical and pathologic findings

目的探讨淋巴管瘤的CT影像学特征及临床意义。方法经手术病理证实且影像资料完整的淋巴管瘤58例,男31例,女27例,均行CT平扫,其中39例行CT平扫及增强检查。回顾性分析不同部位的CT影像学与临床表现,并与手术、病理结果对照。结果淋巴管瘤好发部位依次是疏松间隙、体表软组织、内脏器官。颈-胸间隙23例,腹部间隙17例,关节间隙2例,体表软组织10例,脾4例,肝1例,肾上腺1例,其中影像上表现为单囊23例、多房囊21例、囊实性5例及海绵样9例,单囊及多房囊多见。5例囊实性表现均见于腹部间隙,海绵样表现5例见于体表软组织。58例中病变伴周围血管增粗19例,淋巴结肿大11例,合并出血9例,囊壁钙化2例,破裂1例。39例增强扫描病理有5例轻中度强化。结论不同部位淋巴管瘤的CT影像学表现具有特征性,能为临床治疗提供重要指导。

Objective To study the imaging features of lymphangioma located in different areas and to improve the diagnostic value of imaging findings.Methods Imaging features of 58 cases with lymphangioma proved by surgery and pathology were analyzed retrospectively.CT scans were performed in 58 cases,and enhanced CT scans were performed in 39 cases.Results The lesions were located often in the areas such as loose facial spaces（n=42）,superficial soft tissues（n=10）and visceral organs（n=6）.The CT appearance was unicystic mass（n=23）,multilocular cystic mass（n=21）,cystic-solid mass（n=5）and cavernous（n=9）,uni cystic mass and multilocular cystic mass were the most common.5 cases of cystic-solid mass appeared in the abdominal spaces,cavernous appeared in the superficial soft tissues,19 cases with peripheral vascular thickening,11 cases with enlargement of lymphnodes,9 cases with hemorrhage,2 cases with calcification of cyst wall,and 1 case with rupture.Among 39 cases with enhanced scan 5 cases showed mild to moderate enhancement.Conclusion CT imaging diagnosis of lymphangioma locating in different areas is very helpful and useful in clinic.
