摘要
目的:探讨卵黄囊瘤的多层CT表现,提高卵黄囊瘤的CT诊断准确率。方法:回顾性分析3例病理证实的卵黄囊瘤的多层螺旋CT表现。结果:3例中女1例,男2例;年龄分别为11岁、22岁、35岁;病灶分别位于卵巢、前纵隔、睾丸,其大小分别为11.8cm×11.2cm、15.4cm×7.8cm、6.2cm×4.8cm。多层螺旋CT上平扫病灶均呈囊实性,病灶内出血2例(卵巢、睾丸),钙化2例(卵巢、前纵隔),位于病灶边缘,增强后病灶实性部分逐渐明显强化;3例患者血AFP明显升高。结论:卵黄囊瘤多层螺旋CT表现具有一定特征性,结合血AFP升高有助于术前诊断。
Objective： To study multi-slice spiral computed tomography （MSCT） Imaging appearance of yolk sac tumor and improve its diagnostic accuracy. Methods： MSCT appearances in 3 cases of yolk sac tumor proved by pathology were analyzed retrospectively. Results：Of the 3 patients,one was female and two males. Their ages were eleven, twenty-two and thirty-five respectively. The lesions were located at ovary, testicle and anterior mediastinum respectively. On the plain scan of CT, 3 lesions were solid-cyst masses with hemorrhage and calcification in 2 lesions; solid part showed in homogeneous enhancement. Serum alpha-fetoprotein （AFP） levels were raised obviously in all 3 cases. Conclusion： MSCT manifestations of yolk sac tumor present certain characteristics. AFP level measurement can help to make a diagnosis before operation.
