摘　　要：目的探讨卵巢卵泡膜纤维瘤的CT特征并与病理结果对照分析。方法回顾分析14例卵泡膜纤维瘤患者的CT资料，观察病灶的形态特征、密度特点并与手术病理学表现进行对照。结果14例患者共发现17个病灶，3例多发；病灶呈圆形或类圆形，最大径约32～142mm，平均71．9mm；14个病灶边界清楚，3个病灶边界模糊不清。7个病灶呈实性，密度均匀，CT平扫较子宫肌层呈相对低密度改变，10个病灶密度不均，各有2个病灶内见絮状或囊状低密度区，6个病灶内二者共存，增强扫描实性病灶或病灶实性部分轻度持续强化，1个病灶实性部分明显强化；絮状低密度区可有轻度延迟强化，囊状低密度区无强化。手术病理：所有病灶均见完整包膜，8例大体病灶内见多发囊性坏死区；肿瘤细胞呈类圆形，细胞浆丰富，未见明显核分裂，呈漩涡状排列，周围伴大量胶原纤维，局部组织间隔广泛玻璃样变性，间质弥漫性水肿、黏液样变；盆腔积液9例，胸腔积液1例。结论轻度强化和絮状低密度灶为卵泡膜纤维瘤的主要cT表现，CT检查能较全面显示病理特征和血供特点。Objective To study the imaging features of ovarian fibrothecoma on CT and to compare them with the path- ologic findings to improve the diagnostic accuracy. Methods Fourteen cases of ovarian fibrothecoma confirmed by histo- pathology were analyzed, CT morphological characteristics and density characteristics of the lesions were observed and com- pared with findings of pathomorphology. Results The 14 cases included 17 lesions totally and 3 cases had multiple le- sions,lesions were round or oval;The maximum diameter of tumor in the group range from 32mm to 142ram with mean diam- eter of 71.9mm; 14 of 17 lesions with well-defined margin. 7 solid-appearing mass lesions were showed homogeneous hypo- density to that of muscle layer of uterus on plain CT. 10 of 17 lesions were of inhomogeneous density, solid masses associated with cystic low density or flocculent low density area in each 2 lesions, and 6 lesions had both of them. The enhanced CT scan showed that the solid and solid portion of mass enhanced slightly and gradually, but the solid portion of mass was en- hanced obviously in 1 case. some of area with floeeulent low density enhanced slightly too, the areas with cystic low density were not enhanced. Surgical and pathological findings：All lesions with complete capsule, the area of necrosis were found in 8 cases of pathological body mass samples. The tumor cell was round and their cytoplasm was abundant, division was not been found, then showed whirl-like arrangement and were separated by a great quantity of collagen fiber, part of the fibrous connective tissue hyaline degeneration,hydropie degeneration and mucoid degeneration widely. 9cases were found to havesmall pelvic fluid, and hydrothorax was found in 1 case. Conclusion The pathology and blood supply characteristics of o- varian fibrotheeoma could be revealed by CT examination, the characteristics of enhanced slightly and the area with floceu- lent low density can improve the diagnosis and differential diagnosis of the disease.
