【摘要】：目的分析卵巢甲状腺肿(SO)的MSCT表现,以期提高术前诊断准确率,减少误诊。方法回顾性分析经手术病理证实的18例SO的临床及影像学资料,并与病理结果作对照,分析其相应MSCT表现及误诊原因。结果 18例SO均为单侧附件肿块,呈圆形、椭圆形或分叶状,边界清楚;1例呈囊性,17例呈囊实性,其中7例含有少许脂肪;囊性部分平扫密度较高者14例,实性部分密度较高者(CT值50 HU)14例;17例行CT增强,扫描后实质部分多呈中等(2例)或显著强化(12例)。15例伴有斑点状、线条状或蛋壳样钙化;13例可见腹腔积液,其中1例大量,1例中量,11例少量。镜下可见肿瘤由甲状腺滤泡样结构和富含血管及纤维组织的基质组成,滤泡腔内充满高蛋白凝胶样物质,滤泡上皮为单层立方上皮或柱状上皮,细胞无异型性。结论边界清楚的单侧囊实性肿块、特征性钙化、高密度囊腔及高密度实性部分、实质部分多呈显著强化是SO的特征性MSCT表现,合并胸、腹腔积液及肿瘤抗原升高常常是误诊的原因,结合病理学表现有助于减少误诊。
[Abstract]:Objective to analyze ovarian goiter (SO) MSCT, in order to improve the accuracy of preoperative diagnosis, reduce misdiagnosis. Methods Retrospective analysis of the clinical and imaging features of 18 cases of SO confirmed by pathology data, and compared with the pathological results, analyze the corresponding MSCT features and causes of misdiagnosis. Results 18 cases were SO unilateral adnexal mass, rounded, oval or lobulated, clear boundary; 1 cases were cystic, 17 cases with cystic, 7 cases with a little fat; 14 cases of cystic part plain high density, solid part of high density (CT 50 HU) in 14 cases; 17 cases were enhanced CT, after scanning a substantial part of is moderate (2 cases) or significant enhancement (12 cases).15 cases with mottled, line or eggshell calcification; 13 cases of ascites, 1 cases of a large number, in 1 cases, 11 cases of small matrix microscopically by thyroid follicular structure and tumor rich in blood vessels and fibrous tissue. Composition of follicular cavity filled with high protein gel like substance, follicular epithelium are simple cuboidal or columnar epithelium, cell atypia. Unilateral cystic mass boundary clear conclusion, characteristic calcification, cystic cavity and high density high density solid part, a substantial part of significant enhancement is MSCT features SO with chest, ascites and tumor antigen is often the cause of misdiagnosis, combined with pathological findings helps to reduce the misdiagnosis.

【正文快照】： 卵巢甲状腺肿(struma ovarii,SO)是一种单胚层高度特异性的畸胎瘤,以全部甲状腺组织或甲状腺组织为主所构成的[1],约占成熟型畸胎瘤的2.7%[2,3]。SO发病率相对较低,临床比较少见,无典型症状和体征,术前易误诊。目前国内外关于SO的研究报道还较少,本研究搜集经手术病理证实的18
