目的通过对病理证实的卵巢卵泡膜瘤-纤维瘤患者的CT图像进行回顾性分析,提高术前的诊断准确率。方法回顾性分析15例术前进行CT平扫+增强并经手术病理证实的卵巢卵泡膜瘤-纤维瘤患者的影像学征象。结果 15例患者16个病灶,单发14例(93%),双侧双发1例(7%)。病灶平均长径(7.55±4.45)cm,呈圆形或椭圆形,无分叶,边界清晰,无浸润性表现。囊性11个,实性3个,囊实性2个。边界均较清晰;囊性部分CT值12~26 HU,实性部分CT值27~36 HU;增强扫描囊性部分不强化,囊壁及分隔有明显强化,实性部分有轻度强化在5~14 HU,大部分强化在5 HU左右,未见增粗的血管影。结论根据卵巢卵泡膜瘤-纤维瘤中卵泡膜细胞和纤维细胞两种成分所占比例的不同,囊实性占比不同,肿瘤的边界较清晰,强化不明显。
Objective To retrospectively analyze the CT images of patients with pathologically confirmed ovarian follicular myeloma - fibroma to improve the accuracy of preoperative diagnosis. Methods We retrospectively analyzed the imaging features of 15 cases of ovarian follicular mesenchymoma - fibroids who had undergone CT scan and enhanced CT before operation. Results Fifteen patients had 16 lesions, 14 cases (93%) were single, and 1 case (7%) was bilateral. The average diameter of the lesions (7.55 ± 4.45) cm, was round or oval, no lobulation, clear boundary, no infiltration performance. Cystic 11, solid 3, cystic solid 2. The cystic part of the CT value of 12 ~ 26 HU, solid part of the CT value of 27 ~ 36 HU; enhanced cystic scan does not strengthen the cystic wall and the separation significantly enhanced, the solid part of the slight enhancement in 5 ~ 14 HU, most of the enhancement in about 5 HU, no thickening of the blood vessels. Conclusion According to the different proportion of the two components of the follicular cells and fibroblasts in the ovarian follicular melanoma - fibroids, the proportion of cystic solidity is different, the border of the tumor is clear and the enhancement is not obvious.
