摘要:
目的 探讨进展期胃癌与胃非霍奇金淋巴瘤多层螺旋CT(multi-slice CT,MSCT)动态增强的鉴别诊断价值。方法 对11例胃非霍奇金淋巴瘤和18例进展期胃癌的动态增强MSCT资料进行回顾性分析,比较两者在胃受累部位、各期强化程度、胃壁改变、胃腔改变、黏膜及浆膜改变、器官侵犯、淋巴结转移等方面CT征象的差异。结果 胃淋巴瘤组侵犯72.7%,胃癌组侵犯27.8%。胃淋巴瘤组动脉期平均增加(18.5±7.9)Hu,门脉期平均增加(33.3±10.8)Hu,不均匀强化18.2%;胃癌组动脉期平均增加(40.5±10.9)Hu,门脉期平均增加(55.4±17.9)Hu,不均匀强化83.3%。胃淋巴瘤组溃疡18.2%,胃癌组溃疡77.8%。胃淋巴瘤胃周脂肪间隙受侵0例,胃癌浆膜面受侵55.6%,邻近脏器受侵22.2%。胃壁僵硬:胃淋巴瘤组未见,胃癌组83.3%。胃淋巴瘤肿大淋巴结均匀强化80.4%,直径≥2.5 cm占34.8%,累及>2个引流区占54.5%;胃癌组均匀强化44.6%,直径≥2.5 cm占12.5%,累及>2个回流区16.7%。结论 MSCT动态增强扫描可对胃淋巴瘤和进展期胃癌诊断和鉴别诊断提供有价值信息,并可在一定程度上反应出胃淋巴瘤和胃癌的生物学特点。
Objective To evaluate the application of dynamic contrast-enhanced multi-slice CT (MSCT) in the differential diagnosis of gastric non-Hodgkin lymphoma (NHL) and advanced gastric cancer. Methods Dynamic contrastenhanced MSCT images of 11 patients with gastric NHL and 18 patients with advanced gastric cancer were retrospectively analyzed. The affected areas of stomach, the enriched degree of each phase, the change of gastric wall, cavity, mucosa and serosa, organs involved and lymph node metastasis in CT signs were compared between two groups. Results In gastric NHL group >2 sites of stomach were invaded in 72.7% cases, while in gastric cancer group multiple sites were involved in 27.8% cases. In gastric NHL group, CT value increased (18.5±7.9) Hu on average in arterial phase and (33.3±10.8) Hu in portal venous phase, with heterogeneous enhancement in 18.2% cases;while in gastric cancer group, CT value increased (40.5±10.9) Hu in arterial phase and (55.4±17.9) Hu in portal venous phase, with heterogeneous enhancement in 83.3% cases. Ulceration was shown in 18.2% gastric NHL cases and in 77.8% gastric cancer cases. No case in gastric NHL group had invasion beyond stomach;while in gastric cancer group 55.6% cases had serosa involved, 22.2% had neighboring organs involved. No case of gastric NHL had thickening of gastric wall;while thickening of gastric wall was observed in 83.3% cases of gastric cancer. In gastric NHL group, lymph node metastasis with homogeneous enhancement was observed in 80.4% cases, 34.8% involved lymph nodes were ≥2.5 cm, 54.5% involved lymph nodes had >2 draining areas;while those figures in gastric cancer group were 44.6%, 12.5% and 16.7%, respectively. Conclusion Dynamic contrast-enhanced MSCT provides important information for the differential diagnosis of gastric nonHodgkin lymphoma and advanced gastric cancer.
