| 摘 要： | 目的: 分析十二指肠间质瘤的CT、MRI表现,旨在提高对十二指肠间质瘤的诊断水平。方法: 回顾性分析16例经免疫组化证实的十二指肠间质瘤的CT和MRI表现,其中12例患者行CT检查,4例行MRI检查,将影像学表现与手术病理结果对照。结果: 16例患者中,病理诊断交界性或交界性偏低度恶性潜能5例,低度恶性4例,中-高度恶性7例。影像学表现为十二指肠区类圆形或分叶状软组织肿块,平扫主要表现为实性或者囊实性混杂密度/信号,动态增强后实性肿块或肿块实性部分明显强化,门静脉期持续强化,部分门脉期强化幅度高于动脉期;12例CT检查者中有10例伴有囊变或坏死区呈不均匀强化。16例肿瘤中3例病灶内见钙化,5例病灶内出现气体影。结论: 十二指肠间质瘤的影像学表现与病理特征密切相关;CT和MRI对其定位诊断有重要价值,其中MRI在显示病灶出血、囊变方面更具优势。

| Abstract: | Purpose:To analyze the characteristics of CT and MR of duodenal stromal tumors. Materials and Methods:The CT and MR findings of 16 patients with primary duodenal stromal tumors were analyzed retrospectively,and compared with their pathological results. CT scanning were performed in 12 cases and MR in 4 cases. Results:Pathological report:borderline tumor 5 cases,low-grade malignant tumor 4 cases,moderate /high-grade 7 cases. On CT/MRI,the lesions presented as round and lobulated solid Masses and cystic-solid... |
