| 目的 观察卵巢卵泡膜细胞瘤的MRI表现特点。方法 回顾性分析16例经手术病理证实的卵巢卵泡膜细胞瘤患者的MRI表现,并分析其MRI表现特征及其病理基础。结果 16例患者肿瘤均为单发,呈边缘清晰的球形或边缘呈分叶状的实性肿块,大小2.4 cm×2.4 cm×2.2 cm~15.4 cm×10.6 cm×7.8 cm。MR平扫病灶T1WI呈等或略低信号,T2WI呈欠均匀的等或低信号,内可见点状、片状或裂隙状高信号囊变。增强后病灶轻微强化,延时后强化信号略有增高;1例肿瘤扭转者病灶无强化。14例子宫直肠凹陷可见少量腹水,12例肿块包膜可见少许积液。MRI表现与病理结果相符。结论 MRI能很好地反映卵巢卵泡膜细胞瘤的病理生理特征,对该病的诊断及鉴别诊断具有重要意义。 |

| Objective To analyze MRI appearances of ovarian thecoma (OT), in order to improve the knowledge of this disease. Methods Sixteen patients of OT confirmed histopathologically were analyzed. MRI morphological characteristics and signal intensity of the lesions were observed and compared with pathologic findings. Results The tumor was single, spherical or lobulated solid in shape with some small patchy necrotic area in all 16 patients. MR signal of tumor was close to that of myometrium, low and gradual enhancement could be revealed in the parenchymal phase and delay phase, intraperitoneal fluid was noted in 14 patients and fluid in the plural area of the lesions in 12 patients. MRI manifestations were consistent with pathological findings. Conclusion MRI has characteristic findings, which present the pathologic and pathophysiological changes of OT, therefore is very useful in diagnosis and differential diagnosis of ovarian thecoma. |
