10例胃肝样腺癌的增强CT特征分析

The contrast-enhanced CT features of 10 cases of hepatoid adenocarcinoma of the stomach

目的:分析胃肝样腺癌的CT表现,总结其影像学特征。方法:回顾性地搜集了10例胃肝样腺癌,在增强CT上观察并记录病灶的位置、形态、边缘、有无表面溃疡、有无肉眼可见坏死、增强后的强化方式和均质性等信息,测量每个病灶在各CT期相的CT值。结果:病灶位置以贲门和胃窦为主(各4例),7例表现为局限性、边界清楚的肿块,9例病灶有表面溃疡,8例可见坏死,增强后7例病灶表现为渐进性强化,8例病灶强化不均匀。结论:胃肝样腺癌有表现为局限溃疡型病灶的倾向,坏死成分较多,强化方式与普通胃癌相似。

Objective To investigate contrast-enhanced CT features of hepatoid adenocarcinoma of the stomach.Methods A total of 10 patients with hepatoid adenocarcinoma of the stomach were retrospectively enrolled.The lesions’location,morphology,superficial ulcer,necrotic component,enhanced pattern and homogeneity were analyzed and recorded.The CT values derived from all phases in each lesion were measured.Results The 10 cases of hepatoid adenocarcinoma of the stomach were mainly located in the cardia and antrum(4 cases each).7 cases of them presented as focal and well-defined masses.9 cases showed superficial ulcers and 8 cases showed necrotic component.After contrast enhancement,7 cases showed progressive enhancement and 8 cases were heterogeneous.Conclusions Hepatoid adenocarcinoma of the stomach tends to manifest as focal ulcerative masses with necrotic components.The enhanced pattern of them was similar to common types of gastric cancers.
