This study investigated computed tomographic (CT) features and anatomic bases of gastrocolic ligament involvement in malignant neoplasms of the stomach.
We retrospectively reviewed CT scans of 34 patients known to have gastric malignant neoplasm and gastrocolic ligament involvement. Emphasis was placed on direct invasion, lymph node metastasis, and omental seeding.
CT manifestations of gastrocolic ligament involvement included direct invasion (38.2%, 13 of 34), enlargement of lymph nodes (50%, 17 of 34), "smudged" appearance (26.5%, nine of 34), "omental caking" (5.9%, two of 34), cystic mass (2.9%, one of 34), and varices of the omentum (2.9%, one of 34). We also found that gastric carcinoma and gastrointestinal stromal tumor invaded the transverse colon through the gastrocolic ligament in six patients (17.6%, six of 34).
CT scan is useful for detecting gastrocolic ligament involvement in gastric malignant neoplasm. The imaging features consist of a mass sign, enlargement of lymph nodes, smudged appearance, omental caking, and so on. Gastric malignant neoplasm also may involve the transverse colon through the gastrocolic ligament.
本研究调查了胃恶性肿瘤累及胃结肠韧带的计算机断层扫描(CT)特征及解剖学基础。
我们回顾性分析了34例已知患有胃恶性肿瘤且累及胃结肠韧带患者的CT扫描图像。重点关注直接侵犯、淋巴结转移及网膜播散情况。
胃结肠韧带受累的CT表现包括直接侵犯(38.2%,34例中的13例)、淋巴结肿大(50%,34例中的17例)、“模糊”外观(26.5%,34例中的9例)、“网膜饼状”(5.9%,34例中的2例)、囊性肿块(2.9%,34例中的1例)以及网膜静脉曲张(2.9%,34例中的1例)。我们还发现,6例患者(17.6%,34例中的6例)的胃癌和胃肠道间质瘤通过胃结肠韧带侵犯横结肠。
CT扫描有助于检测胃恶性肿瘤累及胃结肠韧带的情况。影像学特征包括肿块征、淋巴结肿大、模糊外观、网膜饼状等。胃恶性肿瘤也可能通过胃结肠韧带累及横结肠。
