摘要
目的与病理结果对照分析婴儿纤维性错构瘤(FHI)的超声特征。方法应用超声定量分析仪测量经病理确诊的FHI瘤体低回声与瘤体旁正常脂肪组织回声强度(EI),进行定量自身对照分析,并结合病理结果回顾分析FHI组织结构所对应的声像图特征。结果28例FHI共30个病灶,声像图均表现为以高回声为主,混杂条带状或小片状低回声,6例呈“蛇形”表现,13例表现为“栅栏状”(低回声与高回声相间并垂直于皮肤分布);66.67%(20/30)病灶血供稀少,7例可见粗大血管穿行。定量分析结果显示两台超声仪所测瘤体低回声组织与瘤周正常脂肪组织EI差异均无统计学意义(P均>0.05);结合病理结果,推断瘤体内低回声主要成分为脂肪,而高回声主要成分为胶原纤维。结论识别蛇形或栅栏状形态等FHI主要超声特征及瘤体内不同组织回声特点有助于缩小鉴别诊断范围。
Objective To explore ultrasonic features of fibrous hamartoma(FHI)in infants compared with pathological findings.Methods The echo intensity(EI)of hypoechoic and normal adipose tissue adjacent to FHI lesions were measured with ultrasonic quantitative analyzer,and then quantitative self-control analysis was conducted.Combined with pathological results,the ultrasonic characteristics corresponding to the structure of FHI were retrospectively analyzed.Results There were 30 lesions in 28 cases of FHI.Mixed echo,mainly hyperechoic,mixed strip or small pieces of hypoechoic were noticed on ultrasonograms. " Serpentine pattern" was detected in 6 cases,while "palisade"(hypoechoic and hyperechoic were distributed perpendicular to the skin)was found in 13 cases.Totally 66.67%(20/30)lesions had poor blood supply,while dilated blood vessels were observed in 7 cases.Quantitative analysis showed that there was no significant difference of EI of hypoechoic tissue within masses and the normal adipose tissue around masses between two sets of ultrasonic instruments(both P>0.05).According to pathological results,the hypoechoic area within lesion was inferred to be mainly composed of adipose tissue,while the main component of hyperechoic area was collagen fiber.Conclusion Identifying the key ultrasonic features of FHI,such as"serpentine pattern"or"palisade",as well as the echo characteristics of different tissue within lesions could help to narrow the scope of differential diagnosis.
