症的狼疮患者的CT特点。材料和方法：回顾性地研究了从2001年到2005年间有可疑腹部受累或并发症并进行腹CT检查的狼疮患者，所有的CT扫描均在症状出现后的21天内进行。结果：复习了53次CT检查的32例狼疮患者的临床资料和影象学表现发现，与狼疮相关的腹部表现有29例患者，这些表现包括胃肠道血管炎（6例）、急性胰腺炎（8例）和泌尿生殖系异常（13例）、肝脾肿大和腹水。CT上具有“靶型征”的肠壁增厚是胃肠道血管炎的特点，多数病例可发现有轻度胰腺炎（通过CT评分指数提示），5例患者有弥漫性膀胱壁增厚，3例患者还有双侧肾积水和输尿管积水。另外，16例患者有与狼疮无关的其他表现，包括肠梗阻、脾梗塞、阑尾炎和血肿。结论：疑腹部受累的狼疮患者行CT检查对发现腹部症状的主要原因、制定治疗计划和监测合并症是有用的。

MATERIAL AND METHOD: SLE Patients who presented with suspected abdominal involvement or complications and underwent CT between 2001 and 2005 were retrospectively reviewed. All CT studies were performed within 21 days of the onset of symptoms. RESULTS: Thirty-two SLE patients with 53 CT examinations including imaging findings and clinical data were reviewed. There were 29 cases with abdominal findings related to SLE including gastrointestinal vasculitis (6 cases), acute pancreatitis (8 cases), genitourinary abnormality (13 cases), hepatosplenomegaly, and ascites. Bowel wall thickening with target sign in CT is characteristics of GI vasculitis. Mild pancreatitis by CT scoring index was found in most cases. Five cases had diffuse bladder wall thickening and three cases also had bilateral hydronephrosis and hydroureter. Sixteen cases had other findings not related to SLE including bowel obstruction, splenic infarction, appendicitis, and hematoma. CONCLUSION: The common CT findings and complications in SLE patients who suspected abdominal involvement were presented CT is useful for detecting the primary cause of abdominal symptoms, planning treatment, and monitoring for complication. （摘自：Phongkitkarun S, Boonnumsirikij M, Jatchavala J, Tong-u-thaisri P.
