摘要

目的：探讨卵巢囊性腺纤维瘤的CT和MRI表现及其诊断价值。方法：回顾性分析35例经病理证实的卵巢囊性腺纤维瘤的影像资料。卵巢浆液性囊性腺纤维瘤32例，其中3例伴出血坏死，黏液性囊性腺纤维瘤1例，交界性卵巢浆液性囊性腺纤维瘤2例。22例行CT检查，其中18例行增强扫描；13例行MR检查，其中12例行增强扫描。结果：35例患者共36个病灶，2个为实性，6个为囊实性，28个为囊性，其中16个肿瘤为单囊性，12个为多囊性，且6个含有实性结节成分。增强扫描2个含有实性成分的肿瘤明显强化，1个轻度强化，10个未见强化。3个肿瘤内部伴有出血坏死，3个肿瘤伴有囊壁钙化，2个出现“蜂窝征”。结论：卵巢囊性腺纤维瘤内的实性成分在组织病理学上为增殖的纤维组织成分，纤维组织成分的多少决定了肿瘤是囊性或实性。实性肿瘤内含子囊腔、囊性肿瘤伴囊壁增厚，并且实性成分和增厚的囊壁在T2WI为极低信号提示卵巢囊性腺纤维瘤。与CT相比，MRI更有助于判断病变性质，MRI应是卵巢囊性腺纤维瘤的首选检查方法。

Abstract

Objective: To study the CT and MRI findings of ovarian cystadenofibromas． Methods: Thirty-five patients with cystadenofibroma(36 tumors) enrolled into this study. All were confirmed by pathology. In the 35 cases, 33(91.7%) were benign serous cystadenofibroma, 1 was benign mucinous cystadenofibroma(2.7%). Twenty-two cases underwent plain CT scan, among them 18 cases also received contrast-enhanced CT. Thirteen cases underwent plain MR scan, 12 of them received contrast-enhanced MR scan. Results: On CT and MR images, tumors were mainly soild in 2 cases, with mixed components in 6 cases, multilocular cyst in 12 cases, uniocular cyst in 16 cases. After enhancement, the solid components enhanced mildly and the solid component of multilocular cyst also enhanced mildly except two case in which the solid nodule enhanced markly. Three tumors had interior bleeding and necrosis, three tumors had cystic wall calcification, two appeared “honeycomb sign”. Conclusion: Variable amounts of fibrous stromas of ovarian cystadenofibomas made the spectrum of imaging features variable from a purely cystic tumor to a complex cystic tumor. Ovarian cystadenomas are unilocular cystic masses with diffuse or partial thickening of cystic wall and septations, or multilocular cyst with irregular wall component, or multilocular cyst with solid component. CT is helpful to judge the nature of lesions, but difficult to make a definite diagnosis, while MRI due to its excellent resolution should be the imaging modality of first choice for ovarian cystadenofibomas．
