目的:提高对卵巢肿瘤CT表现的认识,总结其诊断依据。资料与方法:回顾性分析经手术病理证实的66例各种卵巢肿瘤的CT表现。结果:(1)肿物内含有脂肪成份及结节状钙化是囊性畸胎瘤的特征性表现;(2)非赘生性囊肿和囊腺瘤的特征性表现为薄壁的囊性肿物,其壁及间隔薄且规则;(3)囊腺癌的特征性表现为囊实性肿块,其囊壁与间隔不规则增厚,可见乳头状突起或不规则块状实性成份。结论:CT是诊断卵巢肿瘤的重要影像学检查手段,对多数卵巢肿瘤,术前一般能做出准确的定性诊断。
Objective: To improve the understanding of CT findings of ovarian tumors and summarize its diagnostic basis. Materials and Methods: CT findings of 66 cases of various ovarian tumors confirmed by surgery and pathology were retrospectively analyzed. Results: (1) The fat content and nodular calcification in the tumor were the characteristic manifestations of cystic teratoma. (2) The non-neoplastic cyst and cystadenoma were characterized by thin-wall cystic masses , The walls and the interval thin and regular; (3) cystadenocarcinoma characterized by cystic solid mass, irregular wall thickening and interval, showing papillary processes or irregular lumps of solid ingredients. Conclusion: CT is an important imaging method for the diagnosis of ovarian tumors. Most ovarian tumors can be accurately diagnosed preoperatively.
