卵巢无性细胞瘤CT表现分析

摘要

Objective To investigate the CT findings of ovarian dysgerminoma to improve the understanding of the disease.Methods A retrospective analysis of 7 cases of pathologically confirmed clinical and radiological data of ovarian dysgerminoma was done.CT and en-hancement scanning were done, and the data was certified by operation pathology.Results 7 cases with cancer were single.5 cases had the solid mass, and 2 cases had cystic mass.Tumor longest diameter was 6.3~19.6cm, 5 cases were more than10cm, and the average length was about 13.2cm.The disease exact parts was enhanced, cystic part no enhancement, and the tumor visible shadow can be seen in tortuous blood vessels in 3 cases.2 cases had pelvic cavity fluid, and 2 patients had pelvic lymph nodes.Conclusion CT manifestations dysgerminoma has some features to help preoperative diagnosis and differential diagnosis of this disease.%目的：探讨并分析卵巢无性细胞瘤的CT表现特点，提高对本病的认识。方法回顾性分析7例卵巢无性细胞瘤的临床及影像学资料，所有患者均行CT平扫及增强扫描，均经手术病理证实。结果7例患者肿瘤均为单发，其中CT表现为实性肿块者5例、囊实性肿块2例。肿瘤最长径6．3～19．6 cm，平均约为13．2 cm，其中10 cm以上者5例。增强扫描病灶实性部分及囊壁较明显强化，囊性部分及坏死区无强化，其中3例肿瘤内部可见迂曲血管影。2例病灶周围界限不清，侵犯邻近脏器，2例伴有少量盆腔积液，2例伴盆腔淋巴结肿大。结论无性细胞瘤的CT表现具有一定特点，有助于对本病的术前诊断及治疗的选择和预后评估。
