高频超声鉴别诊断儿童脐息肉与脐肉芽肿的价值

Differential Diagnosis of Umbilical Polyp and Umbilical Granuloma in Children by Ultrasonography

目的探讨高频超声鉴别诊断儿童脐息肉与脐肉芽肿的临床应用价值。方法回顾性分析经手术病理证实的24例儿童脐息肉患儿(脐息肉组)和40例脐肉芽肿患儿(脐肉芽肿组)的临床资料及超声检查资料,比较声像图特征差异。结果脐息肉组与脐肉芽肿组在患儿年龄和性别等方面的差异均有统计学意义(P<0.05)。脐息肉组的病灶深度、内部回声、病灶血液供应及脐口下方窦道与脐肉芽肿组比较差异均有统计学意义(P<0.05)。脐息肉多表现为病灶深、高回声、乏血液供应/无血液供应、脐口下方窦道存在的实性肿块;脐肉芽肿多表现为病灶浅、低回声、富血液供应肿块、脐口下方窦道缺失的实性肿块。结论高频超声在鉴别儿童脐息肉与脐肉芽肿中有重要价值。

Objective To investigate the clinical value of high-frequency ultrasonography in the differential diagnosis of umbilical polyps and umbilical granulomas in children.Methods The clinical and ultrasonographic data of 24 children with umbilical polyps(umbilical polyps group)and 40 patients with umbilical granuloma(umbilical granuloma group)confirmed by surgery and pathology were retrospectively analyzed,and the differences in their sonographic features were compared.Results There were significant differences in age and sex between patients with umbilical polyp and umbilical granuloma(P<0.05).There were significant differences in the depth of lesion,internal echo,lesion and sinus tract below the umbilicus between the umbilical polyp group and the umbilical granuloma group(P<0.05).Umbilical polyps mostly present as deep lesions,hyper echogenicity,lack/absence,and solid masses in the sinus tract below the umbilicus.Umbilical granulomas mostly present as shallow lesions,hypoechoic,rich masses,and solid masses with absent sinus tracts below the umbilicus.Conclusion High frequency ultrasonography is of great value in differentiating umbilical polyps from umbilical granulomas in children.
