摘要
目的通过分析胃弥散性大B细胞淋巴瘤（DLBCL）的CT表现,提高临床诊断的准确率。方法回顾性分析11例经手术病理证实的原发性胃DLBCL患者的CT表现,包括病变部位、生长方式、胃壁厚度、密度、强化趋势、有无淋巴结肿大、有无腹腔脏器的转移。结果11例患者中4例同时累及胃体、胃角及胃窦,1例同时累及胃体部及胃角,1例病灶局限在胃角,5例病灶局限于胃窦部。10例DLBCL均呈弥漫性胃壁增厚,胃壁最大径为2.7-5.3cm。11例病灶密度均匀,无明显坏死,增强后均呈现持续强化方式。2例患者伴发有龛影,5例患者病灶邻近胃粘膜水肿。3例患者出现腹腔淋巴结多发肿大。结论DLBCL的CT表现具有一定的特征性,能够为术前的鉴别诊断提供帮助。
Objective To improve the accuracy on diagonosis of gastric diffusion large B-cell lymphoma （DLBCL） by evaluating its CT findings. Methods CT images of 11 patients with primary gastric DLBCL, who were proven by surgical operations and pathology, were evaluated retrospectively. CT findings included locations, growth pattern, thickness of gastric wall, attenuations of lesions, the patterns of enhancements, enlargements of lymph nodes and metastasis. Results In 4 patients, the lesions of DLBCL infiltrated into body, angulus and antrum of stomach simultaneously. In 1 paitent, the lesions infiltrated into body, angulus. In the other 6 cases, lesions located at angulus in one case or antum in five cases. In ten DLBCL. The involved gastric walls were diffusively thicken and the maximum thickness ranged from 2.7 cm to 5.3 cm. All lesions were homogeneous without necrosis. After enhancement, the lesions were enhaned persistently. Nich was present in two cases. Edema of gastric mucosa was seen in 5 cases. In three patients, multiple enlarged lymph nodes were present in abdomen. Conclusion The CT findings of DLBCL have definite characteristic and can provide the helpful information for differential diagnosis pre-operatively.
