摘要
目的分析卵巢甲状腺肿(struma ovarii,SO)的CT表现特点及评价CT检查对该病的诊断价值。方法回顾性分析9例经手术病理证实的SO的临床、CT及超声资料,总结SO的CT表现。结果 9例SO其中1例术前CT及超声检查均未见明显结节及肿物,其他8例SO的CT表现为边界清楚的单侧附件区肿块,呈椭圆形或不规则形;3例为囊性,5例为囊实性;囊性部分可见多个大小不等囊腔,不同囊腔密度不同,其中5例呈高密度;增强扫描囊壁及实性部分明显强化;3例伴斑点样或环形钙化;5例伴少量腹腔积液。8例SO超声检查均表现为单侧附件区肿块,界清,呈囊性(2例)、囊实性(5例)或实性(1例)。结论边界清楚的囊性或囊实性肿块、含高密度囊腔、囊壁及实性部分明显强化及有钙化是SO的CT表现特点;CT检查可作为SO有价值的诊断方法。
Objective To analyze the CT features of struma ovarii（SO）. Methods The Clinical date , CT and uhra- sound features of 9 patients with pathologically confirmed SO were retrospectively analyzed. Results Except 1 case of SO didn＇ t show obvious nodule and mass on CT and ultrasound images, other 8 lesions showed unilateral oval or irregular mas- ses with smooth margin. 3 lesions were cystic and 5 were cystic and solid masses. The cystic portions presented well defined multiple cavities, with various attnenuation, and 5 tumors showed hyper attenuation in the cystic portion on CT plain images. The cystic wall and the solid portions were strongly enhanced after injection of contrast medium. Scattered and ring like calcification were found in 3 lesions. 5 patients had ascites. The ultrasound appearances of SO were cystic in 2 lesions, cystic and solid in 5 lesions, solid masses in 1 ease. Conclusion SO features included smooth margin cystic or cystic solid masses with calcification, ascites, hyper attenuation lesions on CT plain images, and marked enhancement in cystic wall and solid part on contrast CT.
