摘要
目的探讨儿童睾丸畸胎瘤及卵黄囊瘤超声声像图特征的差异。方法回顾性分析2015年1月-2019年6月在四川大学华西第二医院进行过超声诊断,经手术及病理证实为睾丸畸胎瘤(30/44)及卵黄囊瘤(14/44)患儿共44例,从病灶大小、位置分布、内部回声、构成成分、肿瘤血供等方面比较两者图像特征的差异。结果 30例睾丸畸胎瘤的最大直径平均值为(24.25±12.13)mm,14例卵黄囊瘤的最大直径平均值为(29.71±18.75)mm,两者大小间差异无统计学意义(F=0.531,P=0.383)。畸胎瘤以囊实性特征最多见(17/30),其次为实性(8/30)和囊性(5/30);而卵黄囊瘤以实性特征最多见(12/14),其次为囊实性(2/14),未出现过囊性肿瘤;儿童睾丸畸胎瘤与卵黄囊瘤在构成成分方面差异有统计学意义(P=0.001),实性征象占比在两组之间差异有统计学意义。畸胎瘤血流分级为0、1、2、3级者分别有9、10、10、1例,卵黄囊瘤血流分级为0、1、2、3级者分别有0、1、4、9例,两组血流分级差异有统计学意义(P<0.001);畸胎瘤较少出现3级血流,而卵黄囊瘤以3级血流最常见。两者在位置分布、肿瘤内部回声及是否存在钙化灶等方面的差异无统计学意义(P>0.05)。结论彩色多普勒超声图像特征对于鉴别诊断儿童睾丸畸胎瘤及卵黄囊瘤具有一定的价值,判断肿瘤内部实性成分及血供情况有助于增强超声医生的诊断信心。
Objective To explore the differences in ultrasonographic features of testicular teratoma and yolk sac tumor(YST) in children. Methods A total of 44 patients were selected, including 30 with testicular teratoma and 14 with YST, whose diagnoses were confirmed by surgery and pathology in West China Second University Hospital, Sichuan University from January 2015 to June 2019. The differences in ultrasonograhic characteristics of the two groups were compared, such as the size, location, internal echo, composition, and blood supply of the tumors. Results The mean value of maximum diameters of testicular teratomas was(24.25±12.13) mm and that of YSTs was(29.71±18.75) mm, with no statistically significant difference between the two groups(F=0.531, P=0.383). In terms of the compositions of the tumors, cystic-solid lesions were the most common in testicular teratomas(17/30), followed by solid lesions(8/30) and cystic lesions(5/30);while solid lesions were the most common in YSTs(12/14), followed by cystic-solid lesions, and cystic lesions did not appear. The difference in the compositions of tumors was statistically significant between children’s testicular teratomas and YSTs(P=0.001), especially in the proportion of solid lesions. In terms of Adler grade of blood flow, there were 9 cases of Adler 0, 10 cases of Adler 1, 10 cases of Adler 2, and 1 case of Adler 3 in testicular teratomas, while there were 0 case of Adler 0, 1 case of Adler 1, 4 cases of Adler 2, and 9 cases of Adler 3 in YSTs. The difference in the blood supply was statistically significant between children’s testicular teratomas and YSTs(P<0.001).Testicular teratomas tended less to behave as Adler 3, while Adler 3 was the most common in YSTs. There was no statistically significant difference in other ultrasonic features, like the location, internal echo, or the existence of calcification(P>0.05). Conclusions Ultrasound has a certain meaning for the differential diagnosis of testicular teratoma and YST in children. By comparing the solid component an
