We determined the MR and CT appearance of ovarian dysgerminoma and correlated our findings with the pathologic features.
CT and MR findings of three patients with ovarian dysgerminoma were retrospectively reviewed and compared with the pathologic findings.
The tumors were divided into lobules by septa that were hypointense or isointense on T2-weighted imaging and showed marked enhancement on Gd-diethylene triamine pentaacetic acid enhanced T1-weighted imaging and contrast-enhanced CT. These septa corresponded to fibrovascular bundles at histologic examination.
CT and MR findings characteristic of fibrovascular septa within solid ovarian masses should raise the possibility of dysgerminomas.
我们确定了卵巢无性细胞瘤的磁共振成像（MR）和计算机断层扫描（CT）表现，并将我们的发现与病理特征相关联。
回顾性分析3例卵巢无性细胞瘤患者的CT和MR表现，并与病理结果进行比较。
肿瘤被分隔分成小叶，这些分隔在T2加权成像上呈低信号或等信号，在钆-二乙烯三胺五乙酸增强T1加权成像和增强CT上显示明显强化。这些分隔在组织学检查中对应于纤维血管束。
实性卵巢肿块内具有纤维血管分隔特征的CT和MR表现应提高无性细胞瘤的可能性。
