The purpose of this study was to determine the CT and MR characteristics of Brenner tumors, rare epithelial neoplasms of the ovary.
CT and MR scans of eight pathologically proven Brenner tumors of the ovary (seven benign, one malignant, and one associated with mucinous cystadenoma) were retrospectively reviewed. The masses were analyzed for location, size, external configuration, internal architecture, enhancement pattern, presence of calcification, and metastatic spread.
The patients' median age was 63 years (range 39-79 years), and the mean size of the tumors was 11.4 cm (7.5-17 cm). All tumors were unilateral and had a well-defined margin. The mass was mostly solid in three, mostly cystic in one, and "mixed" solid and cystic in four cases. The tumors with cystic components (n = 5) were mostly multilocular in appearance (n = 4). All the solid components showed mild homogeneous enhancement on postcontrast CT and MRI. Extensive amorphous calcification within the solid component on CT was seen in five of six cases (83%). No characteristic findings discriminating malignancy from benign Brenner tumor could be found.
Extensive amorphous calcification in a solid mass or solid component in a multilocular cystic mass is a characteristic finding of Brenner tumor of the ovary on CT and MRI.
本研究旨在确定卵巢布伦纳瘤（一种罕见的卵巢上皮性肿瘤）的CT和MR特征。
回顾性分析8例经病理证实的卵巢布伦纳瘤（7例良性，1例恶性，1例合并黏液性囊腺瘤）的CT和MR扫描图像。对肿块的位置、大小、外形、内部结构、强化方式、钙化情况及转移情况进行分析。
患者的中位年龄为63岁（范围39 - 79岁），肿瘤平均大小为11.4 cm（7.5 - 17 cm）。所有肿瘤均为单侧，边界清晰。3例肿块主要为实性，1例主要为囊性，4例为实性和囊性“混合”。有囊性成分的肿瘤（n = 5）大多表现为多房性（n = 4）。所有实性成分在增强CT和MRI上均表现为轻度均匀强化。6例中有5例（83%）在CT上可见实性成分内广泛的无定形钙化。未发现区分恶性布伦纳瘤与良性布伦纳瘤的特征性表现。
实性肿块或多房囊性肿块实性成分内的广泛无定形钙化是卵巢布伦纳瘤在CT和MRI上的特征性表现。
