目的：讨论十二指肠球部充盈缺损的诊断和鉴别诊断。方法：共１２例患者，均进行钡餐造影检查，其中６例进行ＣＴ检查。结果：分别对１２例球部充盈缺损的影像表现进行分析。其中包括球部异物２例；淋巴瘤２例；腺瘤４例；低分化腺癌、类癌、胃窦癌脱入球部、胃息肉脱入球部各１例。钡餐造影显示了１２个病变；ＣＴ检查的６例中，显示５个病变，其中１个漏诊因病变小于１０ｍｍ。结论：十二指肠球部充盈缺损少见，钡餐造影对发现球部病变的大小、形态及腔内结构有重要作用，ＣＴ在病灶的性质病灶周围情况，腔内外侵犯的程度及远处转移方面起着重要的辅助价值
Objective: To discuss the diagnosis and differential diagnosis of duodenal filling defect. Methods: A total of 12 patients underwent barium meal radiography and 6 of them underwent CT examination. Results: The images of 12 cases with bulging defects were analyzed. Including the ball foreign body in 2 cases; 2 cases of lymphoma; 4 cases of adenoma; poorly differentiated adenocarcinoma, carcinoid, gastric antrum into the ball, gastric polyps from the ball in 1 case. Barium meal angiography showed 12 lesions; CT examination of 6 cases, showing 5 lesions, of which 1 missed diagnosis due to lesion is less than 10mm. CONCLUSION: The duodenal bulb filling defect is uncommon. Barium meal angiography plays an important role in detecting the size, shape and intraluminal structure of the lesion in the ball. The CT features of lesions around the lesion, extent of intracavitary invasion and distant metastasis Plays an important auxiliary value
