摘要
目的:探讨原发性卵黄囊瘤的超声表现。方法:回顾性分析经病理证实为卵黄囊瘤的病例发生位置、生长方式,以及超声声像图表现。结果:睾丸局限性病灶11例,其中9例边界清楚,11例形态规则,8例有包膜,5例为囊实回声,2例呈低回声,4例为等回声,1例有钙化,11例血供丰富;睾丸弥漫性病灶5例,均看不到明显的肿块,4例为囊实回声,1例为等回声,2例可见钙化,5例血供丰富。腹部病灶共10例,8例表现为清楚的边界,6例表现为不规则的分叶状肿块,4例表现为圆形或椭圆形肿块,6例为囊实混合回声,2例表现为高回声,1例表现为低回声,1例表现为等回声,1例有粗大钙化,10例血供较丰富。结论:睾丸卵黄囊瘤患者年龄多在2岁以下,睾丸边界清楚的局限性肿块,部分内可见小灶性液性无回声区,血供丰富,腹部的囊实性团块,患者年龄<18岁,实性成分内血供较丰富,液性无回声区分布不均且不规则,无钙化,结合血清AFP升高可考虑卵黄囊瘤。
Purpose： To investigate the sonographic features of primary yolk sac tumor. Methods： Growth pattern and sonographic manifestations of pathological confirmed yolk sac tumors were analyzed retrospectively. Results： Of ll cases testicular local lesions, 9 were with clear boundary, 11 with regular shape, 8 with capsules, 5 with mixed cystic and solid echo, 2 with low echo, 4 with equal echo, 1 with calcification, II with rich blood supply; Of 5 cases of testicular diffuse lesions, no lumps were detected, 4 were with mixed cystic and solid echo, 1 with equal echo, 2 with calcification, 5 with abundant blood supply than contralateral testicular; Of 10 cases of abdominal yolk sac tumor, 8 were with clear boundary, 6 with irregular lobulated masses, 4 with round or oval lumps, 6 with mixed cystic and solid echo, 2 with high echo, 1 with low echo, 1 with equal echo, 1 with thick calcification, 10 with rich blood supply. Conclusion： Patients with testicular yolk sac tumor were mainly younger than 2 years old. Testicular tumor with clear boundary, small focal liquid dark area and rich blood supply, or abdominal cystic mass in patients aged less than 18 years old, with solid ingredients, rich blood supply, uneven and irregular liquid dark area, no calcification, and combined with elevated serum AFP may be considered as yolk sac tumor.
