卵巢纤维瘤16例影像学特点分析

Imaging Features of 16 Patients with Ovarian Fibroma

目的探讨卵巢纤维瘤的影像学特点,以提高术前诊断正确率。方法回顾性分析经病理证实的16例卵巢纤维瘤的临床资料。结果 9例因腹痛或自觉下腹部肿物来诊,1例阴道淋漓流血伴下腹痛,6例体检发现盆腔肿物。16例均行CT检查,6例行MRI检查。16例均为单发肿瘤,呈圆形、卵圆形或分叶状,肿物最大直径平均7.6 cm;肿物密度均匀11例、不均匀5例,增强扫描无明显强化或延迟轻度强化。影像学诊断为卵巢良性肿瘤14例,卵巢恶性肿瘤2例。结论典型的卵巢纤维瘤CT及MRI影像上具有假包膜、变性、包膜下囊变、不均匀T2信号、不均匀强化等特征,有助于术前诊断。

Objective To explore the imaging features of ovarian fibroma to improve the preoperative diagnostic rate. Methods Clinical data of 16 patients with ovarian fibroma confirmed by pathology was retrospectively analyzed. Results Nine patients com- plained of abdominal pain or hypogastrium mass, one patient had abnormal vaginal bleeding and hypogastralgia, and six patients were found with cavitas pelvis mass in a physical examination. All patients underwent CT examinations, and 6 patients underwent MRI exami- nation. All tumours were single, round, oval or lobulated masses, and the average maximum diameter of tumours was 7.6 cm; 11 pa- tients had homogeneous density of tumours, and 5 patients had inhomogeneous density of tumours. Enhancement scanning showed there were not or mild delayed enhancement. Benign and malignant ovarian neoplasms were confirmed in 14 patients and 2 patients respectively by ieonography diagnosis. Conclusion The imaging features of typical ovarian fibroma are pseudocapsule, degenerative changes, chan- ges in peripheral subcapsular cystic areas, asymmetrical T2 signal and enhancement, which are very useful in diagnosis.
