A 65-year-old woman with suspected ascites-associated abdominal distention had elevated CA125 levels. Contrast-enhanced computed tomography to search for the cause of the ascites showed bilateral pleural effusions, ascites, and an ovarian tumor. On magnetic resonance imaging the tumor exhibited a lobulated structure and markedly low signal intensity on both T1- and T2-weighted imaging, with no restrictions on diffusion-weighted images. Progressive enhancement was observed at tumor margins. Meigs syndrome due to fibroma was suspected, and total hysterectomy, bilateral salpingo-oophorectomy, and partial omentectomy were performed. Postoperatively, the pleural effusion and ascites resolved promptly without specific treatment. On pathological examination, the ovarian tumor was diagnosed as a benign Brenner tumor with scattered nests of transitional epithelium within a large amount of stroma. Based on the clinical course, the patient was diagnosed with pseudo-Meigs' syndrome due to a Brenner tumor.
一名65岁疑似腹水相关腹胀的女性,其CA125水平升高。为寻找腹水病因进行的对比增强计算机断层扫描显示双侧胸腔积液、腹水及一个卵巢肿瘤。磁共振成像显示肿瘤呈分叶状结构,在T1加权成像和T2加权成像上均表现为明显低信号强度,弥散加权成像无受限。在肿瘤边缘观察到渐进性强化。怀疑为纤维瘤所致的梅格斯综合征,遂行全子宫切除术、双侧输卵管卵巢切除术及部分大网膜切除术。术后,未经特殊治疗,胸腔积液和腹水迅速消退。病理检查显示,卵巢肿瘤被诊断为良性布伦纳瘤,在大量间质内可见散在的移行上皮巢。根据临床病程,该患者被诊断为布伦纳瘤所致的假性梅格斯综合征。
