多排螺旋CT在原发性消化道淋巴瘤诊断中的价值

The value of multidetector CT in the diagnosis of primary gastrointestinal lymphoma

目的探讨原发性消化道淋巴瘤的多排螺旋CT(MSCT)的影像表现,评价其诊断价值。方法对我院自2009年1月～2011年12月的39例经手术病理和内镜活检病理证实为原发性消化道淋巴瘤的患者行多排螺旋CT的影像表现进行回顾性分析,包括患者的病变部位、强化程度和管壁扩张度的改变以及管壁的厚度。结果消化道淋巴瘤大多表现为消化道管壁的弥漫性增厚,管腔狭窄;粘膜相关性淋巴组织淋巴瘤多见于胃部;39例患者共计39处淋巴瘤,其中胃部17例,小肠9例,食道较罕见;胃部淋巴瘤CT表现呈弥漫浸润型、局限性浸润型、溃疡型,增强后病变为轻度到中度的均匀强化。结论采用多排螺旋CT对原发性消化道淋巴瘤进行扫描,其诊断特点明显,可以对PGIL病变进行准确的分期。

Objective To investigate the diagnosis of primary gastrointestinal lymphoma of the multi-row spiral CT（MSCT） and to evaluate the diagnostic level.Methods 39 patients with pathologically and endoscopic biopsy confirmed the pathological manifestations of primary gastrointestinal lymphoma in patients with multi-slice spiral CT in our hospital from January 2009 to December 2011 were retrospectively analyzed,including the patient＇s lesion,enhanced the extent and expansion of change and off the wall thickness.Results Most of the performancew of Gastrointestinal lymphoma diffuse were gastrointestinal wall thickening,.The mucosa-associated lymphoid tissue lymphoma was more common in the stomach.There were 39 cases of lymphoma in the 39 patients,including 18 cases of stomach.The stomach lymphoma CT findings showed a style of diffuse infiltrative,limitations infiltrative,ulcerative lesions.After it enhanced,it showed from mild to moderate homogeneous enhancement.Conclusion The application of multi-slice spiral CT for diagnosis of primary gastrointestinal lymphoma,its characters are obvious,and it can divide accurately for the staging of the lesion.
