摘　　要：目的：探讨十二指肠Brunner腺腺瘤的CT影像学表现。方法回顾性分析7例经病理证实的十二指肠Brunner腺腺瘤CT表现。结果十二指肠Brunner腺腺瘤表现为密度均匀或不均匀的类圆形或长条形肿块，直径1．5～5．1 cm不等，平均4．1 cm，边缘清晰；CT平扫示肿瘤实体部分密度均与临近肠壁密度相似，增强扫描动脉期均呈中度不均匀强化，门静脉期均呈渐进性强化，密度仍欠均匀。结论十二指肠Brunner腺腺瘤的CT表现具有一定的特点，对其影像特征的认识可减少误诊率，但最终确诊仍有赖于病理诊断。Objective To investigate the CT imaging features of duodenal Brunner′s gland adenoma. Methods CT imaging data of 7 pathologically confirmed duodenal Brunner′s gland adenomas were retrospectively analyzed. Results Duodenal Brunner′s gland adenomas were round or strip-like shaped tumors with homogeneous or heterogeneous density, with a clear margin. The size of tumors ranged from 1.5~5.1 cm, and 4.1 cm in average. The solid part of tumors has a similar density compared to the adjacent intestinal wall on plain CT, and has a moderately heterogeneous enhancement in the arterial phase after contrast agent administration. In the portal venous phase, the tumors were progressively but still heterogeneous enhanced. Conclusions There are some specific imaging features of duodenal Brunner′s adenoma. The cognition of its imaging features makes accurate diagnosis possible, but the definitive diagnosis still requires pathological diagnosis.
