目的:综合分析卵泡膜细胞瘤的MRI影像表现、临床特征及其手术病理结果,以期进一步加深对该病的认识并提高术前诊断的准确率。方法:收集术后病理确诊的卵泡膜细胞瘤10例,分析其影像学特征,包括有无出血、坏死、囊变及钙化,平扫、增强的表现及其与周围组织器官之间的关系。结果:平扫瘤体实性部分表现为T1WI等、低信号和T2WI低信号,部分病灶内可见纤维分隔;增强扫描动脉期多为轻度强化,并有延迟强化的特征。术后9例的病理结果与影像学检查的结果基本符合,表现为病理中的坏死、囊变与MRI上的囊变信号数目、分布基本一致。结论:综合分析卵泡膜细胞瘤的MRI表现与病理学特征,对提高该病诊断的准确率有重要意义。
OBJECTIVE: To comprehensively analyze the manifestations, clinical features and surgical pathology findings of SC in MRI, in order to further deepen the understanding of the disease and improve the accuracy of preoperative diagnosis. Methods: Ten cases of pathologically diagnosed oncocytomas were collected and analyzed for imaging features, including the presence of hemorrhage, necrosis, cystic degeneration, calcification, plain scan and enhancement, and their relationship with surrounding tissues and organs. Results: The solid part of the edema showed T1WI, low signal and T2WI low signal, some of the lesion visible fiber separation; enhanced scan arterial phase mostly mild enhancement, and delayed enhancement characteristics. The pathological results of 9 cases were basically consistent with the results of imaging examination, showing the necrosis in the pathology, cystic change and the number of cystic signals on MRI, the distribution is basically the same. Conclusion: The comprehensive analysis of the manifestations and pathological features of theca cell tumor is of great significance to improve the accuracy of the diagnosis of the disease.
