Mucinous tumors are a common ovarian cystic tumor, having a characteristic finding on MR imaging, the so-called stained glass appearance. We report a rare case of a solidified mucinous tumor of the ovary, which showed unique findings on MR images. The tumor demonstrated hypointensity on T2-weighted images, not stained glass appearance, mimicking ovarian fibrous tumor such as thecoma-fibroma. Histopathological examination confirmed solidified contents of the tumor with numerous septa and diagnosed mucinous borderline tumor/atypical proliferative tumor.
黏液性肿瘤是常见的卵巢囊性肿瘤,在磁共振成像(MR)上有特征性表现,即所谓的“彩色玻璃样外观”。我们报告一例罕见的卵巢凝固性黏液性肿瘤,其在MR图像上表现出独特的特征。该肿瘤在T2加权图像上呈低信号,而非彩色玻璃样外观,类似卵巢纤维瘤,如卵泡膜纤维瘤。组织病理学检查证实肿瘤内容物凝固,有大量分隔,诊断为黏液性交界性肿瘤/非典型增生性肿瘤。
