摘要
目的探讨肠道恶性淋巴瘤的CT和MRI表现及其诊断价值。资料与方法回顾性分析经手术、病理证实的23例肠道恶性淋巴瘤患者的临床及CT、MRI影像学资料;其中CT检查23例,MRI检查5例。结果23例病理组织学结果:均为非霍奇金恶性淋巴瘤,B细胞性淋巴瘤18例,黏膜相关淋巴组织淋巴瘤4例,T细胞淋巴瘤1例;其中肿块型9例(39.1%),浸润型10例(43.5%),溃疡型4例(17.4%)。23例共发现不连续肠道病变42个;肿瘤样病灶23个;肠壁呈向心性增厚病灶15个;肠壁呈不均匀增厚病灶5个。15例伴有腹腔淋巴结受累,胰头受侵1例,脾受侵1例。结论肠道恶性淋巴瘤的CT和MRI表现具有一定特征性,典型的影像学特点,结合临床可以做出正确诊断,并且有助于临床的分期及疗效评价。
Objective To evaluate CT and MRI features and the diagnostic value in primary malignant lymphoma of intestinal tract. Materials and Methods Clinical data,and CT and MRI Imaging of 23 patients with pathologically proved malignant lymphoma of intestinal tract were analyzed retrospectively. Results Non-Hodgkin＇s lymphoma was confirmed in 23 cases,18 of which were B-cell type,4 were mucosa-associated lymphoid tissue lymphoma and 1 was T-cell type. The tumors were divided into nodular type （9 cases,39.1%）,infiltrating type （10 cases,43.5%） and ulcer type （4 cases,17.4%）. 42 intestinal lesions were found in 23 patients. 23 lesions showed as mass,15 lesions showed concentric thickening intestinal wall,5 lesions showed uneven thickening intestinal wall. Celiac lymphadenovarix were found in 15,pancreas involvement in 1 and spleen involvement in 1 case. Conclusion There are some typical features on CT and MRI images in the diagnosis of the intestinal tract malignant lymphoma CT and MRI are helpful in staging of neoplasm and evaluating the effect of treatment.
