摘　　要：目的:探讨儿童节段性大网膜梗死的MSCT影像特点及鉴别诊断。方法:回顾性分析以腹部疼痛就诊并经临床及手术病理证实为节段性大网膜梗死的10例患儿的CT资料。结果:10例患儿均表现为右中下腹前腹壁下方脂肪性包块,其内见稍高密度条索影及点片影,呈特征性“星云征”表现;7例患儿经手术病理证实为大网膜梗死;3例在CT检查后,临床诊断为大网膜梗死,经保守治疗后好转。结论:节段性大网膜梗死影像表现较具特征性,MSCT可明确诊断并与其它需要手术治疗的疾病相鉴别,为临床选择恰当的治疗方法,提供可靠影像学依据。Objective:To explore the characteristics and differential diagnosis of MSCT imaging in children with segmental omental infarction(SOI).Methods:The CT images of 10 patients diagnosed with SOI by MSCT were retrospectively analyzed from June 2014 to December 2018.All cases were confirmed by clinical and surgical pathology.Results:In this group,the patients showed a fatty density below the anterior abdominal wall of the right middle and lower abdomen.The lesions showed a slightly high-density strip shadow and patchy shadow,showing a characteristic‘nebulescence sign’.7 cases were confirmed as SOI by surgery and pathology,3 cases were diagnosed with SOI by clinical after CT examination and improved after non-surgery treatment.Conclusion:The CT imaging features of SOI was of characteristics.Segmental omental infarction can be diagnosed and differentiated from other diseases requiring surgical treatment by use of MSCT,thus to provide a reliable imaging basis for clinical appropriate treatment.
