摘　　要：目的:总结分析婴儿纤维性错构瘤(FHI)的临床及影像表现,并与病理结果对照,提高其诊断水平。方法:回顾性分析经手术病理确诊的20例FHI的临床、CT及MRI表现,对其进行总结分析。结果:20例患儿中男15例,年龄6~36个月,平均(15.3±8.1)个月,病灶最大径20~50 mm,平均(39.2±10.3) cm,病变发生于四肢9例,躯干6例,腋窝2例,阴囊区3例。CT及MRI表现均为含有脂肪的混杂密度或信号包块,边界不清16例;19例为单发病灶,1例为多发病灶;11例病灶表现为“八爪鱼”样外观,7例累及筋膜,1例累及睾丸;6例伴病灶区数条穿行血管,12例增强扫描表现为均匀或欠均匀轻度渐进性强化,6例为周边强化显著,均无包膜及钙化影。结论:FHI的CT及MRI表现典型,与病理具有较高的一致性,术前常规检查可提示诊断。Objective:Analyzing the clinical and imaging features of fibrous hamartoma of infancy(FHI)and comparing them with pathological results,to improve diagnostic accuracy.Methods:A retrospective analysis was performed on the clinical,CT,and MRI findings of 20 cases of FHI diagnosed by surgical pathology,and the results were summarized and analyzed.Results:Among the 20 cases,there were 15 males,with ages ranging from 6 to 36 months(mean age,15.3±8.1 months).The maximum lesion diameter ranged from 20 to 50mm(mean,39.2±10.3 mm).Lesions occurred in the limbs(9 cases),trunk(6 cases),axillae(2 cases),and scrotum(3 cases).CT and MRI findings were consistent,showing mixed-density or mixed-signal masses containing fat,with unclear borders in 16 cases.Nineteen cases presented as solitary lesions,while one case had multiple lesions.Eleven cases exhibited an"octopus-like"appearance,seven cases involved the fascia,one case involved the testis,and six cases showed multiple blood vessels passing through the lesion.Twelve cases demonstrated mild and progressive enhancement with uniform or heterogeneous enhancement,while six cases showed significant peripheral enhancement.None of the lesions had a capsule or calcification.Conclusion:The CT and MRI findings of FHI are typical and exhibit high consistency with pathological findings.Preoperative routine imaging can suggest diagnosis.
