目的探讨卵巢甲状腺肿(SO)的CT表现,提高影像学诊断水平。方法对18例经手术病理证实的SO患者的临床资料进行回顾性分析,并结合术后病理探讨其CT成像基础,总结其CT表现。结果 18例患者中17例(94.4%)单侧发病,1例(5.6%)双侧发病;19个病灶中多房囊性9个(47.4%),囊实性7个(36.8%),实性3个(15.8%),所有病灶边界清楚。囊性及囊实性病灶囊液CT值25～70 HU,平均45 HU,3个实性病灶均明显强化;含脂肪组织病灶6个(31.6%),含钙化者9个(47.4%);2例患者(11.1%)出现少量腹水。结论 SO的CT特征为单侧,多房囊性、囊实性肿块,边界清,囊内液较稠,实性病灶明显强化,常合并有脂肪及钙化,部分患者合并腹水。结合B超、MRI及临床表现术前诊断是有可能的。
Objective To investigate the CT findings of ovarian goiter (SO) and improve the diagnostic value of imaging. Methods The clinical data of 18 patients with SO confirmed by surgery and pathology were analyzed retrospectively. Based on the postoperative pathology, the basis of CT imaging was summarized and the CT findings were summarized. Results Of the 18 patients, 17 cases (94.4%) had unilateral disease and 1 case (5.6%) had bilateral disease. Among the 19 lesions, 9 (47.4%) had multilocular cysts and 7 (36.8% Solid 3 (15.8%), all lesions clear boundary. Cystic and cystic solid cyst fluid CT value 25 ~ 70 HU, an average of 45 HU, 3 solid lesions were significantly enhanced; fat tissue lesions in 6 (31.6%), calcification 9 (47.4%); A small amount of ascites occurred in 2 patients (11.1%). Conclusions The CT features of SO are unilateral, multiple atrophic cysts and cystic solid masses. The boundaries are clear. The intracapsular fluid is thick. The solid lesions are obviously strengthened. The fat and calcifications are often associated with some patients with ascites. B ultrasound, MRI and clinical manifestations of preoperative diagnosis is possible.
