摘要
目的:探讨消化道淋巴瘤的CT特征性表现,提高影像学诊断水平。方法:回顾性分析了经病理学证实的50例消化道淋巴瘤的CT形态学的表现和强化方式,以及累及消化道的范围和侵犯消化道外脏器病变。结果:食管淋巴瘤2例,胃淋巴瘤23例,小肠淋巴瘤8例,大肠淋巴瘤17例。对消化道淋巴瘤的影像学检查、CT表现和CT强化密度作了比较,病变CT平扫CT值(38.68±5.48HU),动脉期CT值(56.48±8.36HU)和静脉期CT值(71.62±10.92HU),病变密度差异有统计学意义(P<0.001)。结论:CT能很好地显示消化道淋巴瘤的病灶形态学改变和CT强化特点,可明显提高消化道淋巴瘤诊断的准确性。
Purpose： To discuss the CT manifestations of the digestive tract lymphoma. Methods： The nonenhanced and contrast-enhanced CT manifestation of 50 patients with pathologically confirmed digestive tract lymphoma were retrospectively analyzed for the morphology and enhancement patterns. The range in the digestive tract was involved and the organs except the digestive tract was infiltratived. Results： The lymphoma located in esophagus in 2 cases, stomach in 23 cases,small bowel in 8 cases and large bowel in 17 cases in the digestive tract. Mean CT value of the tumors was 38.68±5.48 HU on plain scan. Mean CT value of the tumors was 56.46±8.36 HU in arterial phase as well as 71.62±10.92 HU in venous phase after enhancement. The differences of CT value were with statistically significant （P〈0.001） between plain scan and enhanced scan which included arterial phase and venous phase. Conclusion： CT can favourably reveal the characteristic morphology and CT enhancement pattern of the lymphoma in digestive tract. Thus, CT can improve diagnostic accuracy of the lymphoma in digestive tract.
