目的：提高对结肠嗜酸性细胞肉芽肿影像学表现的认识。材料和方法：选择经手术和病理证实7例并有B超、双重造影和CT扫描检查资料完整的病例，回顾分析B超、双重造影和CT等表现。结果：B超检查的7例中，3例表现为均匀性回声增强实质性肿块，2例为不规则形混合回声块影；结肠双重造影有4例显示腔内充盈缺损并管腔狭窄，2例粘膜破坏，2例显示多病灶跳跃性病变；CT扫描中5例显示出病变，2例增强扫描后，见轻度强化。上述各项检查无1例诊断本病。结论：本病的影像学检查手段应以双重造影为主，B超和CT扫描为辅，如密切结合临床和实验室检查完全有可能提高其诊断率，但最后确诊仍需经结肠镜活俭或手术后病理证实。
OBJECTIVE: To improve the imaging findings of colonic eosinophilic granuloma. Materials and Methods: Seven cases with surgical and pathological confirmation and complete B-ultrasonography, double radiography, and CT scan data were selected. The results of B-ultrasonography, double radiography, and CT were analyzed retrospectively. RESULTS: Among the 7 cases of B-ultrasound examination, 3 cases showed a homogenous echo-enhancement and a solid mass, and 2 cases had an irregular-shaped mixed echo block shadow; 4 cases showed a cavity filling defect and a narrow lumen, 2 In the case of mucosal destruction, 2 cases showed multiple lesion jumping lesions; 5 cases showed lesions on the CT scan, and 2 cases showed mild enhancement after the enhanced scan. None of the above examinations diagnosed the disease. Conclusion: The imaging examination of this disease should be based on double angiography, supplemented by B-ultrasonography and CT scan. If it is closely combined with clinical and laboratory examinations, it is possible to increase the diagnostic rate. However, the final diagnosis still requires colonoscopy. Or pathologically confirmed after surgery.
