In a retrospective study of 14 cases of duodenal neoplasms evaluated by computed tomography (CT), there were four primary adenocarcinomas of the duodenum, one lymphoma, five metastatic carcinomas, two duodenal lipomas, one villous adenoma, and one leiomyoma. The CT findings were diagnostic in patients with duodenal lipomas. In 11 cases, a primary origin of the mass was clearly identifiable in the duodenum. Thickening of the bowel wall, tumor necrosis, ulceration, and intraluminal defects were common. The relationship of the masses to adjacent structures was clearly shown on CT scans. Extraluminal extent of the lesion was noted on CT scans in seven patients; however, at surgery only four of six were found to have extramural disease. The presence of adenopathy, liver metastases, and vascular and mesenteric invasion were also demonstrated on CT scans. Twelve patients underwent upper gastrointestinal tract series. A duodenal abnormality was seen in all 12 patients, but the extramural extent and distant metastatic involvement could not be seen on these examinations. CT scans allowed the accurate staging of eight of ten malignant lesions and thus helped in the management of duodenal tumors.
在一项对14例经计算机断层扫描（CT）评估的十二指肠肿瘤的回顾性研究中，有4例原发性十二指肠腺癌、1例淋巴瘤、5例转移性癌、2例十二指肠脂肪瘤、1例绒毛状腺瘤和1例平滑肌瘤。CT表现对十二指肠脂肪瘤患者具有诊断价值。在11例病例中，肿块的原发部位在十二指肠清晰可辨。肠壁增厚、肿瘤坏死、溃疡和腔内缺损很常见。CT扫描清楚显示了肿块与相邻结构的关系。7例患者的CT扫描显示病变有腔外扩展；然而，手术时6例中仅4例发现有壁外病变。CT扫描还显示了腺病、肝转移以及血管和肠系膜侵犯的存在。12例患者接受了上消化道造影检查。所有12例患者均可见十二指肠异常，但这些检查无法显示壁外扩展和远处转移情况。CT扫描能够对10例恶性病变中的8例进行准确分期，从而有助于十二指肠肿瘤的治疗。
