卵巢纤维瘤的CT表现与病理对照分析

CT and Pathological Manifestations of Ovarian Fibroma:A Comparative Study

目的结合病理表现,探讨卵巢纤维瘤的CT分型及其影像特点。方法回顾分析经手术病理证实32例卵巢纤维瘤的临床、CT和病理资料。结果肿瘤形态呈类圆形、卵圆形20例,不规则、分叶状12例。肿瘤最大径范围在1.8-21.4cm之间,平均最大长径为8.1cm。32例中所有肿瘤边缘清楚。密度均匀12例,不均匀20例。增强后30个病灶仅有轻微强化(CT值上升2-8HU),2个病灶无强化。2例增强后肿瘤内见多条纤细血管影。3例合并蒂扭转。伴有腹水者6例。结论 CT能很好显示卵巢纤维瘤的大体形态,卵巢纤维瘤具有良性肿瘤的形态特征,增强后仅轻微强化。

Objective Combined with the performance of Pathology to describe the typing and characteristics on CT of ovarian fibromas. Methods The clinical data and CT findings of 32 patients with histologically proved fibromas were analyzed retrospectively. Results Of the 32 tumors, 20 tumors were nearly round or elliptic and 12 were multilobular or irregular in shape. The size of the tumors ranged from 1.8cm to 21.4cm, and the mean maximum diameter was 8.1cm. Of the 32 cases, all the tumors had clear bordere, 12 cases were of homogeneous density and 20 heterogeneous. 30 tumors enhanced slightly and 2 had no enhancement after contrast medium injection. There were slim blood vessels in tumors in 2 cases after enhancement. 8 cases had tortiles. 6 cases had ascites. Conclusion CT can demonstrate the macropathologic form of ovarian fibroma well. The ovarian fibroma possesses characteristic features of benign tumors, Slight enhancement after contrast medium is its characteristic.
