淋巴管瘤的CT诊断

目的:探讨淋巴管瘤的CT表现及诊断价值.方法:回顾性分析32例经病理学证实的淋巴管瘤的CT资料,并与病理结果对照.结果:根据淋巴管瘤的发生部位将其分为疏松的间隙组(25例,颈部、腋窝、纵隔、腹腔)、内脏组(1例)和体表软组织组(6例,包括胸壁3例、四肢2例和臀部1例).最常见的CT表现为边缘光整的囊性肿块,内有分隔,囊壁菲薄,壁与分隔可强化.结论:淋巴管瘤的CT表现多种多样,主要依赖于其生长部位及内容物的成分.CT对大多数病例定位定性诊断均具重要价值.

CT Diagnosis of Lymphangioma

Objective:To study the diagnostic value and findings of CT in lymphangiomas.Methods:CT findings of 32 cases with pathologically proved lymphangiomas were collected and retrospectively studied.These CT findings and relative pathological results were correlatively evaluated.Results:Based on the location of the lesions,the 32 cases were divided into 3 groups,namely:Loose fascial space group(n=25),lesions found in neck,axilla,mediastinum and abdominal cavity;Visceral group,lesions located in viscera(n=1)and(3)superficial soft tissue group(n=6),including lesions in chestwall for 3 cases,in upper or lower limbs for 2 cases and buttock for 1 case.The most common CT appearances of lymphangiomas were cystic masses with smooth margins and thin walls,septa might be found in some lesions.The walls and septa of the cysts could have been partially enhanced in some cases.Conclusion:CT findings of lymphangiomas were miscellaneous and their appearances depended mainly on the location and components of the lesions.CT was one of the most useful imaging modalities for the localization and nature determination of lymphangiomas.
