胃周韧带腹膜下间隙淋巴管瘤3例MSCT表现及文献复习

目的：结合文献复习，总结胃周韧带腹膜下间隙淋巴管瘤的MSCT表现及其解剖学基础。方法：回顾性分析经手术病理证实的3例累及胃周韧带腹膜下间隙的淋巴管瘤的CT资料。分别观察记录肿块的大小、密度、形态，肿块的强化特点，胃周韧带腹膜下间隙和邻近间隙受累情况。结果：本组3例肿块大小为10．8-22．2cm；肿块呈单房或多房的囊性肿块，2例有囊壁和囊内分隔有强化、1例无强化；1例源于胃脾韧带和脾肾韧带，2例源于肝胃韧带。结论：MSCT可良好显示淋巴管瘤累及胃周韧带腹膜下间隙的解剖细节，有助于累及胃周韧带腹膜下间隙淋巴管瘤的诊断。

CT Findings of the Lymphangioma Involving the Subperitoneal Space of the Perigastric Ligament and Literature Review

Objective：To study the CT imaging features and the anatomic bases of the lymphangioma involving the subperitoneal .space of the perigastric ligament with related literature review. Methods： Three ca- ses with pathologically proved lymphangioma involving the subperitoneal space of the perigastric ligament were reviewed retrospectively. Emphasis was placed on the CT features and its pathways. Results：The lesions range from 10.8 - 22.2 cm. The lesions are single cavity or multiloculated masses, showing fluidity density. On con- trast - enhanced CT images, 2 cases show contrast - enhanced wall and septa in the lesion, and 1 case does not show enhancement. Among 3 cases, the gastrolienal ligament and lienorenal ligament are involved in 1 case. Gastrohepatic ligamen is involved in 2 cases. Conclusions： CT is helpful to reveal the involvement of the subper- itoneal space of the perigastric ligament by lymphangioma.
