【摘要】:目的分析卵巢甲狀腺腫(SO)的MSCT表現(xiàn),以期提高術(shù)前診斷準(zhǔn)確率,減少誤診。方法回顧性分析經(jīng)手術(shù)病理證實(shí)的18例SO的臨床及影像學(xué)資料,并與病理結(jié)果作對(duì)照,分析其相應(yīng)MSCT表現(xiàn)及誤診原因。結(jié)果 18例SO均為單側(cè)附件腫塊,呈圓形、橢圓形或分葉狀,邊界清楚;1例呈囊性,17例呈囊實(shí)性,其中7例含有少許脂肪;囊性部分平掃密度較高者14例,實(shí)性部分密度較高者(CT值50 HU)14例;17例行CT增強(qiáng),掃描后實(shí)質(zhì)部分多呈中等(2例)或顯著強(qiáng)化(12例)。15例伴有斑點(diǎn)狀、線條狀或蛋殼樣鈣化;13例可見腹腔積液,其中1例大量,1例中量,11例少量。鏡下可見腫瘤由甲狀腺濾泡樣結(jié)構(gòu)和富含血管及纖維組織的基質(zhì)組成,濾泡腔內(nèi)充滿高蛋白凝膠樣物質(zhì),濾泡上皮為單層立方上皮或柱狀上皮,細(xì)胞無異型性。結(jié)論邊界清楚的單側(cè)囊實(shí)性腫塊、特征性鈣化、高密度囊腔及高密度實(shí)性部分、實(shí)質(zhì)部分多呈顯著強(qiáng)化是SO的特征性MSCT表現(xiàn),合并胸、腹腔積液及腫瘤抗原升高常常是誤診的原因,結(jié)合病理學(xué)表現(xiàn)有助于減少誤診。
[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.
