目的：探讨多层螺旋CT小肠造影（MSCTE）在小肠肿瘤诊断中的应用价值。方法回顾性分析经手术病理证实的45例小肠肿瘤的MSCTE影像表现，总结其影像学表现特点。结果45例小肠肿瘤中，良性肿瘤9例，其中脂肪瘤6例，影像表现为腔内含脂肪低密度肿块影；腺瘤2例，表现为腔内均质的软组织肿块；回肠系膜淋巴管瘤1例，表现为不规则囊性病灶。常见的恶性肿瘤34例，其中腺癌14例，表现为肠壁局限不规则的环形增厚，中度不均匀强化；间质瘤11例，表现为较大的软组织肿块，以腔外生长为主，密度不均匀，中度或明显强化，常伴有囊变、坏死；淋巴瘤9例，肠壁不规则增厚或形成软组织肿块，累及肠段较长，均匀轻中度强化，常伴有肠系膜、腹膜后淋巴结肿大。少见的恶性肿瘤2例，转移瘤1例，表现为多发肠壁不规则增厚，明显强化，腹壁出现转移性结节；类癌1例，右下腹不规则肿块影。结论 MSCTE在小肠肿瘤诊断与鉴别诊断中有较好的临床应用价值。

Objective To investigate application prospects of Multi-slice computed tomography Enterography(MSCTE) in diag-nosing small intestine tumor (SIT). Methods MSCTE findings were retrospectively analyzed in 45 cases of SIT diagnosed patho-logically after surgery and were summarized in terms of imaging features. Results Of all 45 cases of SIT,9 were benign ones and 6 were lipoma,characterized by low-density mass shadow in intestinal cavity;2 were adenoma,characterized by homogeneous soft tissue mass in intestinal cavity;1 belonged to ileac mesentery lymphangioma,characterized by irregular cyst-like focus;34 were the most common type of malignancies,14 of which were adenocarcinoma,characterized by localized ring-formed thickening of in-testinal wall with moderate heterogeneous enhancement;11 were mesenchymoma,characterized by soft tissue mass relatively big in measurement,which primarily grew outside the intestinal cavity,with heterogeneous density,moderate or distinct enhancement ac-companied frequently by cystic degeneration and necrosis;9 were lymphoma,characterized by irregular thickening of intestinal wall or formation of soft tissue mass,which affected intestine in relatively greater length,and which took on homogeneous slight-moder-ate enhancement accompanied frequently by enlargement of retroperitoneal lymph nodes and those in mesentery. 2 were rare ma-lignancies and 1 was metastatic tumor,characterized by multiple irregular chickening of intestinal wall with distinct enhancement and presence of metastatic nodules in abdominal wall;1 was carcinoid tumor characterized by irregular mass in right lower quad-rant. Conclusion It suggests that MSCTE has good prospects of clinical application in diagnosis and differential diagnosis of SIT.
