摘要
目的 探讨CT、US检查对儿童过敏性紫癜胃肠道损害的诊断价值。方法 分析 14例经临床和实验室检查确诊为过敏性紫癜患者的CT、US表现。年龄 6个月至 14岁 ,男 9例 ,女 5例。14例均以急腹症就诊 ,如阵发性腹痛、呕吐 ,且均出现在皮肤出血斑之前。 7例行CT检查 ,其中 1例行增强检查。 9例行US检查 ,同期行CT和US检查者 2例。结果 CT、US检查均显示多发或单发的节段性肠壁水肿 ,对称或不对称性肠壁增厚 ,境界模糊不清 ,肠腔狭窄 ,8例伴有腹腔积液。 1例增强检查显示病变肠壁轻度均匀强化。结论 过敏性紫癜消化道损害急性期CT和US检查最重要的价值是与需要手术治疗的其他急腹症相鉴别。在出现本病特征性的临床表现之前 ,典型的CT、US表现可以提示诊断 ,同时可发现本病比较常见的并发症肠套叠、肠梗阻或肠穿孔 ,从而为临床确定治疗方案提供影像学依据。
Objective To evaluate the usefulness of CT and US in the diagnosis of gastrointestinal involvement in children with rheumatoid purpura. Methods Abdominal CT and US findings in 14 cases of clinical and laboratory confirmed of rheumatoid purpura were analyzed. There were 9 males and 5 females with the age ranged from 6 months to 14 years. All patients was hospitalized because of acute abdominal emergency, and the clinical presentations included paroxysm of abdomen pain, vomiting, without skin rashes and subcutaneous hemorrhage. CT examination was done in 7 cases, and contrast enhancement was performed in 1 case. Abdominal ultrasound was done in 9 cases. Both CT and US were done in 2 cases. Results All patients demonstrated multiple or single areas of bowel-wall thickening, localized intraluminal narrowing, mesenteric edema, and liquid in abdominal cavity by CT and ultrasound. Conclusion Abdominal CT and US examination have important values in differential diagnosis of acute abdominal disorders in children patients with rheumatoid purpura. Before appearing skin rashes, classical picture can help for the diagnosis and clinical treatment.
